Is it possible to light a car from another battery. How to properly light a car from another car? Is it possible to light a car with a gun

Let's analyze in detail and step by step how to light a car. These steps will come in handy in order to start your car without ruining or burning anything.

So, in order to light a car, you will need: wires for lighting and a donor car from which you will light your car.

Donor search and preparation for connection

Step 1. Find a donor car.
It is easy to do this in any city, since the world is not without kind people.

Open the hood of your car. Stand next to the car. Pick up the lighting wires and show them to the drivers of passing cars.

You can ask a neighbor in the parking lot or call your acquaintances or friends and ask them to light their car. Even if you don't have lighting wires, brake your cars anyway and ask to light your car. Many drivers carry wires with them and will help you.

Step 2. Show the driver of the donor car where you have the battery under the hood (which side).

This is necessary in order for the driver to drive his car on the side (where he has a battery) as close to your car as possible.

Step 3. Check on your car that the alarm is disabled (disable by pressing the button on the remote control). Turn off the ignition on your car and turn off all consumers: heated glass, stove fan, lights, headlights, etc.

We connect cars

Step 4. Tell the driver of the donor car to turn off his engine, turn off the ignition, and open the hood of the car.

Step 5. Take the wires for lighting the car with clips ("crocodiles") at the ends. Note that there are two clips on each wire. Most often, the wires for lighting the car are of a different color (so as not to confuse the polarity), usually red and black. The black wire is needed to connect to the "-" negative terminal of the battery (the so-called ground). Red goes for the "+" positive terminal of the battery. On the battery, the positive terminal is usually a red cap.

If there is no cap, then find the red (pink) thick wire that fits the battery.

Step 6. Take the red wire in your hands and with one crocodile clip you cling to the “+” positive terminal of the donor car battery. The second clamp at this time (while connecting to the terminal) must be in your hand (IMPORTANT: you must not touch the plus clamp to other parts of the car). Then connect the second clamp of the red wire to the "+" positive terminal of your vehicle.

Step 7. Take the black wire in your hands and hook it with one clamp to the "-" negative terminal of the donor car battery. Then hook the second clip to the exposed thick metal of your car's engine.

If it is difficult to find open metal under the hood of your car (covered with a casing, there is only one plastic around), then in this case you will have to connect the wire clip to the "-" negative terminal of your battery. This should be done very carefully, with outstretched arms and as far away from the battery as possible. Why? When the battery terminal clamp is touched, a spark runs through.

This spark can ignite the hydrogen mixture that is released from under the battery cover. This is rare, but it does happen, so stay away to avoid splashing from the battery.

We start our car

Step 8. The wires are connected. The donor vehicle is muted. We checked that everything is connected correctly. The ideal option is for the driver of the donor car to wait 5-10 minutes. This time is most often enough for your battery to charge a little from someone else's battery (take charge). But usually people don't have free time (and so thanks for helping). And not everyone will agree to give up all their battery power.

Therefore, after connecting the wires, you get into your car and start it (by turning the key or pressing the button). If you have a car with a manual transmission, be sure to depress the clutch (this will make it easier to start the engine). Do not crank the starter for more than 20 seconds. If the car does not start, then wait 20-30 seconds and turn on the starter again.

Why won't the car start?

The most common reason your car won't start (the starter motor turns easily, not with difficulty) is that the spark plugs are flooded with gasoline (gasoline engine). In order to blow them out, modern injection engines have a special spark plug blowing mode. You just need to press the gas pedal all the way and, keeping it pressed, crank the starter for 10-15 seconds.

Fuel will stop flowing into the engine and the spark plugs will dry out. Then you wait 30 seconds and start your car again.

The car started

Step 9. Your car's engine has started. GREAT! Release the clutch pedal carefully (gearshift in neutral if you have a mechanic). They let go. Include the dimensions on your car (this must be done so that there are no power surges when disconnecting the clamps). Get out of the car and go to the hood.

Step 10. You start to disconnect the wires. Do everything in reverse order. Disconnect the "-" negative terminal of the black wire from your vehicle, then from the donor vehicle. Disconnect the "+" positive terminal of the red wire from the donor vehicle and then from your vehicle. Be sure to thank the person who helped you)).

Step 11. Run your car's engine for at least 10 minutes before driving so that your battery can be recharged from the alternator during this time. Warm up your car's engine thoroughly and then shut it off. The car must start again.

Why didn't the car start?

If the car does not start, then, most likely, problems with the car generator (does not give charging) or the battery is so old that it does not accept charging (does not charge), which means it is time to change the battery.

Therefore, there is no point in lighting the car, since you will get on the road and will not be able to start again without assistance. I already talked about operating a car in winter, so I hope you remember what you can and cannot do with a car in winter.

Can I light a car with a gun?

Yes, you can, without a difference, which is an automatic transmission or a manual transmission, because this is a type of transmission of your car, and not an engine.

Can I light a cigarette when the car is running? Yes, you can, but only on old Russian cars without electronics, and if everything is done correctly. On modern cars, you cannot light a cigarette from a running car!

If you have a modern car, then do not let the engine light when the engine is running, otherwise you may damage the electrical equipment of your car. Why? When another car is lit from your car (you are an auto-donor), then at this moment there is a strong voltage drop in the network of your car.

If the engine of your car is started at this time, then at the moment of voltage drop there will be a sharp load on the generator. Such a stressful shock can deactivate the electrical equipment of your car (generator, block controller, etc.).

Therefore, you do not need to give a light from a running car. Even on an old car, so that the generator does not fail, before lighting up from a running car (auto-donor), it is necessary to turn on the headlights on it so that the bulbs (which are easier and cheaper to replace) would burn out from power surges (which are easier and cheaper to replace) than an expensive generator ...

More questions

Is it possible to light a cigarette from an injection vehicle?

Yes, you can, the main thing before lighting a cigarette is to turn off the engine of the injection donor car so as not to burn the electrical equipment.

Is it possible that when the car is lit, the battery of the donor car will be discharged (drained)?

Yes, maybe, especially if the donor car's battery is old or already discharged. Therefore, before giving someone a light (a neighbor in a parking lot, parking lot, in the yard, etc.), start your car first, warm it up, and only then let's light another car. If your battery is in good working order, then there is no need to be afraid that another car will land it instantly, but do not allow to drive your battery for half a day.

Is it possible to light a jeep from a small car?

It may work, but most likely not. Because the battery capacity of the small car will not be enough or it will be enough to turn the starter once. It should be borne in mind that battery capacities differ depending on the power and dimensions of vehicles. For example, a Jeep Cherokee with a 3.0 engine is equipped with a standard 90 A / h battery. And on the Matiz with a 0.8 liter engine, there is a weak battery with a capacity of 35 A / h. The more powerful the car, the higher the current when cranking the starter. Therefore, it is better to light cars with approximately equal power and dimensions, or it is better to light a Matiz from a jeep, but not vice versa.

Can I light a car with a diesel engine?

Yes, you can, if the battery voltage is the same: 12 and 12 volts. You just need to know and remember that diesel engines, unlike gasoline ones, require a much higher starting current. Therefore, it is necessary to light a car with a diesel engine from cars with a large-capacity battery, otherwise the donor car's battery will be discharged or its capacity will not be enough to start the diesel engine.

That's all for today. Now you know how to light a car!

Almost every car owner was faced with a situation when the car's battery was discharged after an overnight stay in the cold. It is most efficient to start the car by lighting it from another battery. At the same time, it is important to properly light a car from another car and not damage the electronic and electrical circuits of both cars.

Signs and Causes of Battery Discharge

Signs of a low battery level in a car are:

  • sluggish operation of the starter, while the control lamps of the car shine very dimly;
  • with a large discharge of the battery, the current is not enough even to turn the starter;
  • when you try to start the engine, the solenoid relay crackles, and all the lamps on the instrument cluster go out.

Similar symptoms are observed with insufficient contact of the wires of the on-board network at the battery terminals. Therefore, first of all, it is necessary to check the reliability of the installation of these elements on the battery.

The video from the channel VAZ 2101-2107 REPAIR AND MAINTENANCE demonstrates the procedure for measuring battery leakage current.

The reasons for the discharge of any battery are:

  1. Insufficiently efficient operation of the generator - a weakly tensioned belt, failure of the components of the generator itself.
  2. Damage to electrical wiring, due to which there is an increased consumption of electricity. In this case, the battery can be discharged even in a car with the keys removed from the ignition lock.
  3. A common cause of discharging is additional alarms, which consume a lot of current due to design features (for example, two-way communication systems) or due to improper installation.
  4. With infrequent use of the machine, a gradual self-discharge of the battery occurs. Therefore, it must be periodically removed from the car and charged from a special charger.
  5. Over time, a lead-acid vehicle battery ages and begins to lose its capacity due to irreversible chemical processes taking place in it. In winter, as the ambient temperature decreases, the drop in capacity increases even more. The service life of modern batteries rarely exceeds 4-5 years.
  6. A deep discharge, which is extremely harmful to the battery, can occur due to the dimensions lamps left on, the interior lighting or the radio tape recorder.

Ways to start a dead battery

A reliable way to start a car with a dead battery is lighting up - supplying voltage to the on-board network from another source. Such a donor can be a battery installed in another car or in a special portable device called a Jump Starter (booster). In many large cities, services have appeared that offer the service of a car mechanic's departure with the possibility of lighting a car from a booster device.

Booster model Telwin Speed ​​Start 1212

The automatic booster is a compact device with a built-in lithium-ion battery capable of delivering starting current from 400 to 4000 A (depending on the model). Such a starter battery is capable of giving at least 20-40 starting pulses, but this depends on the degree of battery charging and starting conditions.

An alternative way is to start the engine with a dead battery from the tug. But this option is only suitable for cars with a manual transmission. It is strictly forbidden to tow cars equipped with automatic transmission.

Requirements for wires for lighting

A special cigarette lighter is used to connect the battery terminals. It consists of thick wires with clamps at the ends, with which the cables can be picked up to the battery terminals. Since a high current flows through the wires between the batteries when starting, they heat up to significant temperatures.

Therefore, the cables must meet the following requirements:

  1. Only copper stranded conductor is allowed.
  2. The cable cross-section for starting a standard gasoline engine with a cylinder capacity of up to 1.5 liters must be at least 16 mm2 (corresponds to a diameter of 4.5 mm). For universal wires, the cross section is about 70 mm2 (diameter 9.5 mm).
  3. The wires must have insulation resistant to temperature extremes. Silicone is considered a suitable material.
  4. The optimal length of the wires is about 2 meters, since this will allow the engine to be started from a car parked at a long distance. In this case, it is necessary to ensure a low voltage drop - no more than 2.3 V for every 1.5 meters of wire at a current of 200 A (or 1.3 V at a current of 100 A).
  5. The cable and alligator connection must have a reliable electrical contact and not serve as a place for voltage drop or overheating. Ideally, the joint should be solid or well-soldered tin solder.
  6. The wiring must be guaranteed to operate at a current of at least 200 A - the minimum threshold for lighting cars. To do this, there must be sharp teeth on the working part of the clamps, which will ensure reliable contact with the battery terminals.

General view of wires for lighting

The consequences of trying to light up with wires of inadequate quality will be very sad. In the best case, the cables themselves will burn out, in the worst case, all the wiring under the hood of both cars may catch fire.

Safety engineering

Before starting work, you need to remember the basic nuances of how to properly light a car from another car.

Regardless of the time of year, when performing lighting, you must follow the rules:

  1. Before starting the start, you must remove the keys from the lock and open the doors in a car with a dead battery. This is necessary in order to avoid the involuntary closing of the central lock when voltage is supplied to the on-board network from the donor.
  2. The voltage of the batteries and the on-board network of cars must be the same - 12 or 24 V.
  3. The negative "crocodile" from the donor battery should be attached only to the engine crankcase or to an unpainted car body element with a dead battery.
  4. Before lighting a cigarette, it is necessary to check the condition of a dead battery. If it freezes, the procedure is prohibited, as this may cause the destruction of such a battery. The check is carried out visually through the plugs in the upper parts of the battery cans. The frozen electrolyte looks like a fairly liquid jelly. This test cannot be performed on maintenance-free batteries.

How to properly light a car

Most car owners do not disconnect the wires from the donor car battery. Problems usually do not arise, but to fully guarantee the preservation of the functionality of the electronics, it is better to remove the wires from the battery terminals.

Before starting work, it is necessary to establish the type of vehicle electronics.

Release before 1990

The simplest electronic circuits are used on cars with a carburetor fuel supply system or the first injection systems, including foreign cars produced before the early 1990s. Such cars can be safely lit without removing the battery from the donor car.

To start the engine, follow these instructions step by step:

  1. Place cars nearby, bodies should not have points of contact.
  2. Do not turn off the donor engine.
  3. Connect the positive terminals first and then the negative terminals.
  4. The donor driver needs to maintain an increased speed of up to 2-2.5 thousand rpm to ensure the operation of the battery charging system.
  5. The owner of the second car must wait a few minutes for the battery to start charging.
  6. Start the engine and disconnect the terminals, first negative and then positive. If, after several attempts to start the engine, it does not work, then it is necessary to check the ignition and fuel supply system. In some cases, the car is started with the discharged battery removed, which is connected to the on-board network later.

Connection diagram for lighting, indicating terminals and connection points

Issue 1990-2000

With the advent of injection engines, the number of electronic units in the circuit of cars has sharply increased, which react very sensitively to sudden changes in voltage in the on-board network.

If the battery is dead on a production car before the beginning of 2000, then the connection procedure is as follows:

  1. Place the vehicles side by side, bringing the engine compartments as close as possible. Car bodies should not touch.
  2. Muffle the power unit of the donor vehicle.
  3. Disconnect the wires from the battery terminals on the donor.
  4. Connect the positive terminal of the discharged battery with the positive terminal of the donor battery.
  5. Connect the negative terminal of the donor to the body or to the crankcase of the engine of another car. The bodywork must be free of paintwork. When this wire is connected directly to the negative terminal of a dead battery, all the energy of the charged battery will go to recharge.
  6. Wait a few minutes for a small recharge of a dead battery.
  7. Switch on the ignition and try to start the engine. If several attempts to start the engine are unsuccessful, then stop further attempts to start the engine.
  8. In case of a positive result, it is necessary to warm up the unit and recharge the dead battery a little.
  9. Stop the engine after 6-8 minutes of operation.
  10. Disconnect the negative and then the positive wire.
  11. Try to start the engine from the native battery and let it run for 10-15 minutes to fully warm up the engine and start charging the battery.
  12. At the end of the trip, check the condition of the battery and electrical wiring, fully charge the battery with the charger.
  13. In case of constant repetitions of the problem, you need to more carefully check the wiring for leaks or replace the battery.

Release after 2000

The optimal procedure for starting a modern car with a diesel or injector from a battery or booster is as follows:

  1. Place the battery or booster device next to the vehicle. When starting from the booster, you should carefully study the manual for its operation.
  2. Connect the wires in the sequence - the positive pole from the donor to the positive terminal of the car, and then - the negative wire to the engine crankcase.
  3. Start the unit and let it run for 5-7 minutes without disconnecting the booster or the second battery.
  4. Turn off the engine and disconnect the negative wire, and then the positive wire.
  5. Remove the booster device or additional battery and start the engine from the standard battery of the machine.
  6. After the end of the trip, recharge the battery and check the operation of the on-board network.

In what cases it is impossible to light a cigarette

It is not allowed to start the engine of one car from the on-board network of another in the following cases:

  1. Do not light a car with a smaller battery. A difference of up to 15% is permissible, otherwise a rapid discharge of the donor battery will occur.
  2. Mismatch of battery voltages. Do not connect 12 and 24 volt batteries to each other.
  3. The appearance of a smell of burning wiring or fuel is a signal to terminate the procedure until the reasons for its occurrence are clarified.
  4. It is not recommended to use cars with automatic transmission as a donor due to the risk of damaging the control unit. On such cars, it is necessary to disconnect the battery from the mains and only then try to light another car from it.
  5. A gasoline engine must not be started from a diesel vehicle battery.
  6. It is forbidden to use connecting wires of small cross-section and cables with damaged cores or insulation. The use of such wiring will lead to a short circuit and failure of the electrical systems of both vehicles.

Many manufacturers prescribe in the on-board literature a ban on the use of a car battery as a power source for another car. If such information is indicated, then it is better not to use your car as a donor, since you can lose warranty service for the car in case of a breakdown due to this procedure.

The car owner needs to be prepared for any surprise. If the car does not start due to a dead battery, you will need help from an external power source. To receive a charge from the battery of another car is called "light a cigarette" in professional slang. To perform the operation, you need to know how to properly "light" the car. What do you need to use the donor's help, what instruments are needed, what is the sequence of operations?

Having received a request for help to start the engine of another car, the question involuntarily arises: is it not harmful to "light up", to use your car as a donor. If your new battery is fully charged, the car works, you have some free time, it is unethical to refuse help. Batteries must be of similar capacity and voltage, the donor machine is of the same or higher class.

To "light" another car from your own car is harmful and dangerous if the operation is carried out as follows:

  • during the "lighting" of the car, the donor stands with the engine running;
  • in the process of "lighting" on the auto acceptor ignition works and electrical appliances are turned on;
  • the donor is a battery of lower capacity;
  • the sequence of operations when assembling and removing connecting wires is broken;
  • small cross-section wires with poor-quality insulation, faulty contacts or "crocodiles" are used;
  • safety measures are not followed.

If you carry out the operations correctly, there will be no harm to the battery and the on-board network of another car. You cannot "light" from an old battery. You should refuse the donor's service if its battery leaks, an acidic smell is felt.

How to properly "light" a car

A modern car has a complex electronic filling that requires stability of electrical parameters. Experts and practitioners have developed an algorithm on how to safely "light" one car from another. The sequence of assembling the circuit and removing the wires is important when lighting from the donor's car. During the recharging period, a current of 300-400 A flows through the circuit, the created short circuit can bring a lot of troubles.

How to properly "light" your battery from another car? First of all, you need to get good quality connecting wires for lighting. May they always be in the trunk. The set includes a black wire for connecting to minus or ground, red - plus. The wires are massive, their cross section is at least 16 squares. There are crocodile clips at both ends. Choosing thinner cables can result in severe heat burns and even fire. In Chinese products, thin wires are often hidden under thick insulation.

When choosing a car for "lighting", make sure that it has a working battery of equal or greater capacity, but with the same output voltage. Before "lighting" your battery, check its serviceability. Do not recharge if the battery is frozen or leaking.

Before you "light" a car from another car, you need to be sure that the car is fully operational, but the battery is dead. If the music is turned on in the cabin, the lights are on, the windshield wipers and lifts work, but the engine does not start, you cannot “light” the car. Why? The reason is not the battery.

Signs of a broken battery:

  • strained sounds are heard when turning the ignition key;
  • Control panel lights are off or dim
  • uncharacteristic sounds are heard under the hood.

To "light" the car battery, you must install it in an open place, with the possibility of access for another car. The machine used as a donor must work at XX in order for its battery to be maximally charged.

How to "light" a car from another car with wires

So, you have selected a suitable car, placed it conveniently to "light up" the wires. He has already worked, recharging the battery. How to correctly assemble the scheme for the transfer from the donor?

  1. Switch off ignition and all onboard electrical consumers on both vehicles.
  2. Assemble the circuit - connect the positive terminals of the batteries with a red wire. On the donor, we connect the black terminal to the battery terminal, the second end to the acceptor body, in a place where there is no paint, to ground.
  3. The donor's engine starts up, the battery is recharged for 5-7 minutes. How much to "light" depends on the air temperature.

After recharging, the donor is completely muffled, the wires are removed and a test run of the auto recipient is carried out. Result:

  • the engine starts and runs smoothly;
  • the start did not occur, the starter did not have enough energy to spin the motor;
  • the starter works well, but the car won't start.

In the event that there is not enough charge, you should re-light the car within 10 minutes, according to the same scheme. If there is no result, you should call for technical assistance. Reason: the malfunction is not in the battery.

The circuit is analyzed in reverse order. First, the wire is removed to ground, then the positive terminals are released.

How to "light" a car from another automatic car

Let's figure out whether it is possible to "light" a car on the machine, use, as a donor, another machine, an automatic machine? What is the difference? Electronic control systems are designed for constant voltage. If the battery has become completely unusable, after replacing it, a re-tuning of the computer is required. Is it possible to recharge a dead battery locally from another car with a machine gun and how to give, "light" another car?

It is necessary to understand the principle of energy transfer. "Light up" a car - transfer the battery charge of one car to the battery of another, with a lower charge, through the wires. Cars do not work, ignition is off, on-board systems are off. With a properly assembled circuit, there is no danger of damage to the on-board system of the donor and acceptor.

When connecting the wires with which you need to "light" the car, you must observe the connection sequence and polarity. If you mix up the terminals, a short circuit with bad consequences will occur.

"Light" the car correctly automatic machine:

  • Remove the key from the ignition and leave the door open. (At the moment of power supply, the machine will sound and the door lock will be locked). Place both machines on the parking brake. The auto donor should be warmed up by running the motor at XX for more than 5 minutes.
  • First connect the positive wire, then the negative wire to the donor car.
  • Perform the same operation on your Auto, making sure that you connect the poles correctly.
  • Get behind the wheel and start the engine. Set the engine to 1500 rpm, leave the engine running.
  • Before removing the "cigarette lighter", you must turn on the resistance on your car to smooth out the voltage surge. Do not turn on the lighting lamps - they may burn out. You can turn on the heating of the glass.
  • Remove the wires first from the negative terminals, then from the plus.

So you can "light" another car with a manual transmission from an automatic car.

There are posts on the Internet on the forum with information on how to "light up" a donor's machine. Is it possible to “light up” from a running car? If the donor battery works with a broken circuit, it does not supply the on-board networks, a voltage surge will not occur. When the engine is running, only the battery will be recharged, which discharges the charge, "lighting up" the dead battery. But by the time the driver makes a test run, the donor's car must be muted. Otherwise, there may be a power surge, failure of expensive equipment.

"Lighting up" a car is a simple process, but there are certain rules, we suggest watching the video.

How to properly "light" a car with a dead battery

How many cases when it is required to "light" the car, but the circumstances of assistance change, the sequence of some operations. Much depends on the type of car - diesel or gasoline, automatic or mechanic. Experienced drivers have a well-established scheme of how to properly "light" their car from another, which donor will fit and which will not.

So, the connection of the two batteries is completed, we checked the correctness again so as not to get tangled in the wires it is accepted: red cables always connect plus, black goes from the minus of the donor to the mass of the recipient.

The most common way to properly "light" a dead car from another working one. It is necessary to start the donor engine for the time required to recharge the dead battery. This can be anywhere from 5 to 20 minutes. Muffle a serviceable car. Remove the wires and carry out a test run. It may be necessary to warm up the car a little more, to "light" the car with a dead battery, if the starter turns lazily. As soon as the engine is started, the generator will start charging the battery, and in 10-15 minutes you can drive.

Another way is for experienced drivers with a conventional manual transmission, a minimum of electronics. The wires are connected. How to correctly and quickly give a “light” to a car owner with a new battery? Run the donor motor for 5-6 minutes. Try to start a faulty car. Attempt to start does not exceed 15 seconds, interval of one minute. As soon as the engine starts working, leave both cars switched on and linked to the donor for 3 minutes. Before disconnecting the wires from the terminals in the on-board line, turn on the resistance to smooth out the voltage surge.

"Lighting" is an undesirable, emergency and dangerous operation. Is it possible to "light" from the car if the donor driver has doubts about the health of the battery? Owner's concerns are justified:

  • when the frost outside is below -20 0;
  • the class of the idle machine is higher;
  • higher capacity battery;
  • diesel engine.

How to properly "light" a car from another car, look at the video.

How long is it reasonable to "light" the car

The "lighting" method reanimates a car with a dead battery, but without other malfunctions. The time spent on recharging and starting, in each case, depends on the degree of discharge of the battery, the ambient temperature. As a rule, lighting a car from another car, assembling the circuit and removing the equipment takes about 30 minutes. Reoperation may take the same amount of time. A person who is in a hurry on business should take this circumstance into account.

How to properly "light" a car from another battery

In our fast age, when “time is money” for every car owner, the search for a donor can take a long time. It is much easier to have your own external battery, which will help out in difficult times. These devices include a starting booster, a car battery charger, and a backup battery. Then, will it be possible to "light" the battery without a car, but according to the same principle as taking energy from another car? Yes.

To "light" the battery, you need a car booster. The device is pocket-sized, but has enough energy to cope with starting the engine when the battery is discharged to zero. The device has 2 modes, it can "light" the battery, recharge it, or it can take over the power supply instead of a completely discharged battery.

The booster can "light" not only a car battery, it is used to charge electronic gadgets when the network is unavailable. But its cost is high. Basically, such portable compact chargers are used to "light" a car when the battery loses its charge and capacity during long journeys. Special starter chargers are compact, serve to "light" the car from another battery. Assembling the correct power supply circuit from an external source is relevant, this is the same "lighting" from an external battery.

The main problem with using external energy storage devices is their ability to make just a few starts. But there are professional network boosters. But in case of force majeure, “lighting” the car from an external battery is salvation.

This situation often catches even experienced drivers by surprise: one in a hurry forgot to turn off the light, another has an old battery, and a third has a problem with the generator ... In short, it can happen to anyone. How to properly "light" a car? It turns out that not even all experienced motorists still know how to do it safely, and even our dear girls, who just got their license yesterday ...

Let me remind you that for lighting use two wires with crocodile clips, which connect "in parallel" the terminals of the batteries of two cars - yours and the "suffering". That is, plus to plus, minus to minus. Just? Not really. In any case, any publication on this topic immediately generates a flurry of controversy and comments - they say, everything is wrong, everything is wrong!

Myth 1. A neighbor refuses to give a light from his battery

It's not about greed - he fears for his car. Because servicemen and electricians of all stripes speak to him with one voice, they say, there is no need to do this. Say, your car was not designed so that someone would cling to the battery with wires, and besides, it was connected at the same time it is not clear where ... There are plenty of scarecrows about how, after such operations, the standard electronics of the donor car were out of order. How true they are all, in this case, does not matter: just do not be surprised that the neighbor does not want to take risks.

In the old days, such an operation was in the order of things. Muscovites lit up from Zhiguli - and that's okay. But that was a very long time ago, when cars were incomparably simpler. And today they have become akin to a computer and therefore too pampered. And the risk of damage from power surges is really great.

Myth 2. Lighting a car with a disconnected on-board terminal of the donor car

It's much safer to light a cigarette. But even in this case, the greedy neighbor can be understood. Firstly, on many cars, the batteries are hidden under plastic shields, and today you cannot find a suitable tool in the average trunk. And secondly, many modern cars categorically do not tolerate even a short-term battery disconnection. After that, the owner will have to contact the service, losing time, money, and if not at all lucky, then the guarantee. We are talking, of course, about machines of a high price category, but not everyone wants to carry out such experiments, even on inexpensive machines. What if they also became moody?

Myth 3. The sequence of actions when lighting a car

It is necessary to connect the external battery in parallel to the standard one - this requires thick connecting wires. Thin ones are absolutely useless to start.

The sequence is as follows:

  1. Connect the positive (+) jump lead to the positive (+) lead of the donor booster battery and then to the positive (+) lead of the discharged battery.
  2. Connect the negative (-) cable to the negative (-) terminal of the auxiliary battery, and then to the engine block of the stubborn vehicle. While it is best to grab onto the lifting eye to raise the powertrain, it is usually easy to find. As a last resort, if there is no access to the "metal", connect it to the (-) terminal of the battery of the dying car.
  3. Make sure the cables do not touch the fan blades or other moving parts of the motor.
  4. Try to start a moody motor. If it "worked" - disconnect the "negative" wire (first from the capricious car, then from the donor battery), and then the positive wire in the same sequence.
  5. Let the revived car run - in general, do not jam it right away. Without a recharged standard battery, he will not have life anyway. Later it would be good to understand the reason for the "dying" of the standard battery.
  6. And if there are no normal thick wires? Jokes are jokes, and finding them today is a big problem. What is on sale is 99.9% disgusting Chinese ephemera with thick insulation and tiny wires inside (see photo below). In extreme cases, if the thick wires have not been found, you will have to use what you have, but the "pleasure" will have to stretch for at least 15-30 minutes, until the charges of the two batteries are a little equal. After that, you can try to start the engine.

Myth 4. The sequence of connection when lighting a cigarette is not important ...

The difference is purely security. If you first connect the negative wire, and then accidentally let go of the positive wire connected to one of the batteries, then it is very likely that it will touch a metal part of the car when it falls. This is a short circuit! It also happens that the already connected "crocodile" suddenly unhooks from the terminal - the same consequences. But if you first connect the "pluses" to each other, then the accidental fall of the negative wire is not so dangerous. Unless, of course, it falls exactly on the positive terminal, which is unlikely. Myth 5. Should I start the engine of the donor car?
Opinions differ here. Many people believe that, having paralleled the batteries, it is worthwhile to drive the engine of the donor machine a little in order to recharge both its battery and the dead one in this way. And only after that, turning off your engine, try to start up someone else's. Skeptics object: they say, if a serious malfunction "sits" in a discharged battery (short circuit in banks, etc.), then in an unfortunate scenario, the donor generator may "be offended" by this. Therefore, my opinion is: there is no need to start the engine of the donor car.

Myth 6. Complete prohibition of "smoking"

This is where everything goes! In a modern car, a completely obvious tendency can be traced: to block as much as possible all the ways of the car owner's access to his guts. However, even today, lighting from another car is actually prohibited: only a +12 V socket is provided for the consumer, and you cannot connect anything to it - read the instructions! And if, by the simplicity of your soul, you let the master-receiver know that you gave someone a light, then ...

Myth 7. We light up from autonomous lithium launchers

Every motorist at least once faced the problem of a dead battery.

This unpleasant situation can be caused by banal weather conditions, headlights not turned off in time, or a long car parking. The availability of special wires (crocodiles) for experienced car owners greatly facilitates the task of starting the engine. This article will discuss how to light a battery from another car in a similar situation.

Absolutely any car with a charged battery can become a full-fledged donor. Thanks to these wires, you can connect a power source from another vehicle without removing it.

In order to protect the technique from various problems and not get injured yourself, you should rely on a certain order of actions, which will be discussed in more detail below.

Step-by-step process of "lighting" from another car

First, you need to determine the true causes of the inoperative engine. The starter may not show signs of life at all, and electrical devices (headlights, on-board computer, etc.) may work properly. In this situation, the battery has nothing to do with it. You just need to get into the car and check thoroughly the entire electrical system.

If it's all about a dead battery, then all that remains is to light the battery, especially if it happened along the way.

For this you need:

  1. Connect the battery from the donor car to the battery terminals on the inoperative car, strictly observing polarity(An important point is the correct positioning of vehicles relative to each other. The length of the wires should be sufficient with a margin, and the car bodies could not touch). It is worth paying attention to the power of both batteries, they must be identical. The positive terminals are connected to each other, but the negative terminal from the donor car is connected to the body of the recipient car (to any of its unpainted parts).
  2. After the first step has been taken, it is necessary to secure both vehicles (with a hand brake) and turn on the ignition and electrical appliances for both cars(This is done in order to protect devices from sudden surges in electricity and their failure for this reason).
  3. Next, the wound-up cars should be left to idle for 10 minutes at an engine speed of 1500 - 2000 rpm. As a result, the battery of the auto-recipient will be recharged a little and the ignition will be turned off for a few minutes. If necessary, this operation is repeated one more time.
  4. As a result, the car is left working and the second car too. An important point at this stage is the absence of pressing the accelerator pedal. The motors must run smoothly, there must be no unnecessary voltage surges in the system that can damage the electrical equipment of both participants in the procedure.
  5. It remains only to disconnect the wires from the terminals in exactly the reverse order of the connection. First, disconnect the black (-) wire, then the red (+). At this final stage, it is also recommended to include glass heaters and ventilation systems. Do this to soften the surge in power. It is better not to use the headlights at the moment, as they can simply burn out.

This scheme for reanimating a car from a car battery - a donor is fully capable and simply irreplaceable in difficult times

You can light a car from another car in some other ways:

  • Lighting a dead battery from a donor car with the engine running. Negative consequences can be: generator breakdown, short circuit or failure of any electrical devices in the car
  • The second way to light a cigarette from another battery is to move the battery to the place of a dead power source. This method only works with carburetor engines. After the engine is started, without turning off its batteries, they return to their original places, where the discharged battery begins to be powered by a running generator.

Is it possible to light a cigarette from cars of different brands?

The device of electrical systems for all cars is generally identical, but the wiring diagrams can vary significantly. To understand how to properly light a car from a car of another brand, having studied the instructions for its operation.

There may be no consequences, but serious problems may arise, up to the replacement of a burned-out on-board computer or a fire.

This procedure has a number of features:

  • It is forbidden to light a diesel car from a gasoline engine(Diesel engines require significantly more electrical costs to start).
  • The case of a shrunken battery must be completely sealed and not be damaged.
  • Choose a car rationally- donor based on the volume of the engine.

What actions should not be taken during the lighting procedure

Most motorists allow this procedure to be carried out from their car only with the engine running. On the contrary, such a decision does more harm than good.

This feature can be explained on the basis that at the moment of transfer of the electric charge to the car - the recipient at the terminals of the car - the donor, the charge will make a significant leap down. Due to this side effect, various overloads in the work of its electrical systems can occur. The greatest risk in this situation is the owners of injection vehicles.

Safety when lighting a cigarette from another car

It is always worth remembering that the battery is explosive and contains dangerous acid inside it. How to properly light a car and not get injured will be discussed below.

Before carrying out the operation, you must make sure that the electrolyte level is normal and that it is not frozen. The level is easy to determine visually by opening the plugs in the cans, you can also check for freezing visually.

All procedures must be performed with glasses and gloves.

Acid contact with unprotected skin may cause severe burns or a terrible allergic reaction.

Evaporating hydrogen is constantly present around the battery, so there should be no open fire or sparks nearby.

Lighting device (crocodiles) must be in good working order and have no holes.

It is necessary to strictly observe the polarity when connecting and exclude the possibility of mutual contact of different terminals.

Before starting the procedure, you should pay special attention to the tightness of the body of a shrunken power source; in the event of mechanical damage or cracks, the procedure cannot be carried out. It is also necessary to study the indicators of the capacity and density of the battery. How to check the battery density can be found on the Internet. Timely maintenance of modern car brand batteries will save you decent money and always be confident in the reliability of your vehicle.
