- this article is about , how to properly light a car.

The end of autumn for motorists is marked by many problems associated with the upcoming operation of the car in the winter. And very often the problem of the weak becomes the main one.

Basic rules for lighting cars

To solve this problem, you need to know a few simple rules.

First, it should be remembered that a mixture of hydrogen and oxygen is released in the battery during operation. Such a mixture of gases explodes from the smallest spark, destroying the case and spraying around the electrolyte containing sulfuric acid.

Battery exploded

That is why it is forbidden to use open fire and smoke during start-up. For prevention, it is also recommended to cover the battery with a thick cloth: this will reduce the risk of injury during an explosion.

It should be remembered that if the electrolyte gets on the skin, it must be washed with plenty of water, and then immediately consult a doctor. If the electrolyte gets on the clothes, it should be removed immediately, and the skin areas under the clothes should also be washed with water for prevention.

What should you know about the cable for car lighting?

It should create minimal losses. To do this, he himself must be copper and rather thick.

It is known that for a passenger car with a one and a half liter engine, the minimum cable cross-section should be about 16 square meters. mm. The cable must be in a strong, but at the same time soft insulation that does not crack in the cold. Connecting the terminals to the cable - only soldering, no crimping!

At the same time, the terminals for best contact should be quite "toothy". The length of the wires should be enough for comfortable work, but it should be remembered that the shorter the wires, the less their resistance.

How to smoke from another car

So, all precautions are observed, you can begin to "revive" the engine. First of all, we put both cars on parking brake("Handbrake"), placing them so that they do not touch each other (have no electrical contact).

The correct position of cars when lighting up

It will not be superfluous to remind you that the battery from which the “lighting” is made should be similar to the one that “revives”: have a voltage of 12 V and be no less than a dead battery in capacity. Trying to start with a much smaller battery can result in best case by discharging both batteries.

When lighting a car, be sure to turn off the ignition on both cars and connect the discharged battery and the charged one with “pluses”, while first connecting the cable to the dead battery, then from which the engine will start.

Then, in a similar way, we connect the “minuses” of the batteries with the difference that on the “animated” car, the “crocodile” of the “cigarette lighter” must be mounted directly on the “mass” (unpainted part of the body or engine).

Correct connection of the cigarette lighter cable

Remembering that during start-up a spark will inevitably jump at the point of contact, we find the connection point as far as possible from the gas lines. We also pay attention to the fact that the cable does not get into moving parts when the engine is running.

We start the engine of the "reviving" car. After five minutes of idling, we increase the speed to 2000. Now we start the “animated” car. The starter activation time should not exceed 15 seconds, the interval between attempts should be 30-45 seconds.

Important! After the engine has started, do not rush to disconnect the systems: let them work for another five minutes. After that, you can disconnect the system by stopping the engine of the "donor" car and not stopping the engine of the "revived" car, but this must be done carefully: in the electrical system of the sick car, after removing the load (shutdown), the voltage will inevitably increase.

It will not be long, but still, it is better to load the system with something to avoid a power surge. You can turn on a powerful consumer of energy, for example, a heater or heating rear window. Headlights should not be used for this: although they are a powerful consumer, they can simply burn out during a power surge.

Disconnect the cables in the reverse order: first the "negative" wire, then the "positive". After that, you can carefully remove the tissue covering the battery - electrolyte may be on it.

How to properly light a car - video:

For a “busy” engine to better charge the battery from - it is necessary to let it work well for 10-20 minutes.

Almost every car owner has experienced a situation where accumulator battery the car was discharged after overnight parking 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 correctly light the car from another car and not cause damage to the electronic and electrical circuits both machines.

Signs and causes of a drained battery

Signs reduced level car battery charging are:

• sluggish operation of the starter, while pilot lamps car light is very dim;
• with a large discharge of the battery, the current is not enough even to crank the starter;
• when you try to start the engine, there is a crackling of the retractor relay, and all the lamps on the instrument cluster go out.

Similar symptoms are observed when there is insufficient contact of the on-board network wires 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 VAZ 2101-2107 REPAIR AND MAINTENANCE channel demonstrates the procedure for measuring battery leakage current.

The reasons for the discharge of any battery are:

1. Not enough effective work generator - weak tensioned belt, failure of the nodes of the generator itself.
2. Damage electrical wiring, due to which increased consumption electricity. In this case, the battery can be discharged even on a car with the keys removed from the ignition.
3. A common cause of discharge is additional alarm which consumes high current due to design features (e.g. two-way communication systems) or incorrect 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, automotive lead acid battery ages and begins to lose its capacity due to irreversible chemical processes taking place in it. In winter, as the ambient temperature drops, the drop in capacity increases even more. The service life of modern batteries rarely exceeds 4-5 years.
6. Deep discharge, which is extremely harmful to the battery, can occur due to the size lamps left on, interior lighting or radio.

Ways to start a dead battery

A reliable way to start a car with a dead battery is to light it up - supply voltage to the on-board network from another source. Such a donor may be a battery installed on another car or in a special portable device, which is called jump starter(booster). In many major cities services appeared that offer the service of an auto mechanic leaving with the possibility of lighting a car from a booster device.

Booster model Telwin Speed ​​Start 1212

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

An alternative way is to start the engine with a dead battery from a tugboat. But this option is only suitable for cars with mechanical box gears. Cars equipped with automatic transmission are strictly prohibited to be towed.

Lighting wire requirements

A special cigarette lighter is used to connect the battery terminals. It is a thick wire with clips at the ends, with which the cables can be hooked to the battery terminals. Because when you start by wire between batteries goes high current, they heat up to significant temperatures.

Therefore, cables must meet the following requirements:

1. It is allowed to use only copper stranded conductor.
2. 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 (corresponding to a diameter of 4.5 mm). For universal wires, the cross section is about 70 mm2 (diameter 9.5 mm).
3. Wires must be insulated against temperature extremes. suitable material considered silicone.
4. The optimal length of the wires is about 2 meters, since this will allow you to start the engine from a car parked at a far distance. At the same time, 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 connection of the cable and the "crocodile" must have a reliable electrical contact and do not serve as a place for a voltage drop or overheating. Ideally, the joint should be solid or well soldered with tin solder.
6. The wiring must be guaranteed to work at a current of at least 200 A - the minimum threshold for lighting cars. To do this, the working part of the clamps must have sharp teeth that will ensure reliable contact with the battery terminals.

General view of wires for lighting

The consequences of trying to get a light 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 ignite.

Safety

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

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

1. Before starting, you must remove the keys from the lock and open the doors in a car with a dead battery. This is necessary to avoid inadvertent closure. central lock when voltage is supplied to the on-board network from a donor.
2. The voltage of the batteries and the on-board network of the machines must be the same - 12 or 24 V.
3. The negative "crocodile" from the donor battery must be attached only to the engine crankcase or to an unpainted element of the car body with a dead battery.
4. Before lighting up, it is necessary to check the condition of the 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. Frozen electrolyte looks like pretty liquid jelly. On the maintenance-free batteries such verification is not possible.

How to properly light up a car

Most car owners do not disconnect the wires from the battery of the donor car. Usually there are no problems, but to fully guarantee the preservation 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 used on vehicles with carburetor system fuel supply or the first injection systems, including foreign cars produced before the beginning of the 1990s. Such cars can be safely lit without removing the battery from the donor car.

To start the engine, you must follow the following instructions step by step:

1. Set the cars side by side, the bodies should not have points of contact.
2. The donor engine should not be turned off.
3. Connect the positive terminals first and then the negative.
4. The driver of the donor needs to maintain an increased speed of up to 2-2.5 thousand 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 fails, 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, with indication of terminals and connection points

Issue 1990-2000

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

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

1. Install cars side by side, as close as possible engine compartments. Car bodies must not touch.
2. mute power unit donor vehicle.
3. Disconnect the wires from the battery terminals on the donor.
4. Connect the positive terminal of the discharged battery to the positive terminal of the donor battery.
   
5. Connect the negative terminal of the donor to the body or to the engine crankcase of another car. body element should not have paintwork. When this wire is connected directly to the negative terminal of a dead battery, all the energy of a charged battery will go to recharge.
6. Wait a few minutes for a small recharge of a dead battery.
7. Turn on the ignition and try to start the engine. If several attempts to start do not lead to success, then further attempts to start the engine should be stopped.
8. In the case of a positive result, it is necessary to warm up the unit and slightly recharge the dead battery.
9. Shut off 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 a charger.
13. In the case of constant repetitions of the problem, you need to more carefully check the wiring for leaks or replace the battery.

Issues after 2000

Optimal Starting Procedure modern car with a diesel or an injector from a battery or a booster is as follows:

1. Place the battery or booster next to the vehicle. When starting from a booster, you should carefully study the instruction manual for its operation.
2. Connect the wires in 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. Stop the engine and disconnect the negative wire, and then the positive one.
5. Remove booster or additional battery and start the engine from the regular battery of the car.
6. After the end of the trip, recharge the battery and check the operation of the on-board network.

In what cases you can not smoke

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 use a car with a smaller capacity battery. A difference of up to 15% is acceptable, otherwise the donor battery will quickly discharge.
2. Battery voltage mismatch. Do not connect 12 and 24 volt batteries to each other.
3. The appearance of the smell of burning wiring or fuel is a signal to terminate the procedure until the causes of its occurrence are clarified.
4. It is not recommended to use cars with automatic transmission as a donor because of the risk of damaging the control unit. On such machines, 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 electrical systems both cars.

Many manufacturers prescribe in the on-board literature a ban on using a car battery as a current 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 car in the event of a breakdown due to this procedure.

We light a car from a starting-charger, from another car. Detailed instructions.

Situations on the roads are different, and it is worth being ready for each of them. Even if your car is in in perfect order, you may need the assistance of another driver on the road. In this article, we will tell you everything about lighting a car, and also supplement it with diagrams for the most detailed disclosure of the issue.

Most people, if they find a completely dead battery, prefer not to risk it and call the emergency service, or ask fellow travelers to take the car in tow. Indeed, there are some subtleties, not taking into account which can do more harm than solve the problem. In addition, many are afraid of whether it is possible to give a light from their car at all, or then there is a risk of stalling yourself.

How to give a light to another car?

One of the most important points - before starting the process of lighting, be sure to turn off the engine. In case of non-fulfillment, so many simple rule you risk a lot: failure of the car's generator and / or relay.

Now it is necessary on the car that will light up (which has a dead battery) disconnect the negative terminal from the battery and, after it is disconnected, disconnect the positive one as well.

Now carefully connect the wires, incorrect connection - you risk making a short circuit. In order for everything to go according to plan, first disconnect the negative wires, and only then start connecting the wires. If you do everything in order, then you should not be afraid that the planted battery will discharge the charged donor battery. For those who are afraid to get confused, it works Golden Rule- start removing the minus terminals, then the plus.

Now let's move on to the connection. We take the "+" terminal and attach it to the donor. The second terminal "+" to the second car. Now we take the “-” from the donor and connect it to the second car (to the engine). It is important to remember that the "-" donor attached to a discharged battery will instantly discharge another battery. So, we connect the “-” terminal to the engine, but as far as possible from moving parts, and even more so from the heat pipe. In the process of connection, sparking occurs in most cases.

It is necessary to light up until the engine starts. After that, immediately rearrange to medium speed, let the engine run for 15 minutes and turn it off. Then disconnect the wires. Now it remains to return the "ground" wire and move on.

For a more accurate description of the process, we present a scheme for lighting a car from a donor car.

How to properly light a car with automatic transmission?

There is a widespread opinion among motorists that it is absolutely impossible to light a cigarette with an automatic transmission, but what is there to light a cigarette, you cannot tow a car at a speed of more than 10 km / h. But here completely different components of the machine are affected. Remember that automatic transmission does not apply to the generator, the battery, and you can start the car through the cigarette lighter.

How to light a car injector, cargo?

If you have an injection car with a more complex electronic battery release system, therefore, not disconnected from the power supply system, as this is fraught with breakdown or failure of electrical equipment (“brains”).

For recharging injection car First you need to recharge the battery. This is not difficult to do, but you need to carefully watch what you are doing. So, we take and connect in turn "+" and after them "-":

• We take the "+" starting wires with red clips and connect the terminals of the discharged battery to the "+". We connect the second positive terminal to the donor battery;
• We take the “-” starting wires with black handle-clips and connect them to the negative terminal of the donor battery, and the other end to the discharged battery;
• Wait a few seconds and you can gradually start the car, immediately after the plant we let it work at medium speed for 10 minutes, which warms up the engine and recharges the battery;
• We turn off the engine;
• First, remove the negative wire from the discharged battery and then remove the second minus, then remove the pluses in the same way;
• Start the car and drive to the destination without stopping, so as not to stall again.

Can a diesel car be lit?

In case it is necessary to start diesel car from another car, you will need the same or larger engine motor vehicle diesel, since diesel-powered vehicles require much more energy to start.

How to light a car from a battery without a car?

Of course, you can start the car without another donor car, but only if you take care in advance and purchase a launcher. Charger. Yes, it costs a certain amount, but it takes up a minimum of space in the car and will solve the problem on the road without the participation of passing cars.

So, connect the starter-charger to the mains, put the switch on “start” and connect the “+” of the device to the “+” terminals, and the “-” to the engine block, as close as possible to the starter.

Next, start the car and, as soon as the engine is running, turn off the device. When you reach your destination, charge the battery. By the way, this device is suitable for absolutely all cars and is safer than lighting from another car.

Is there a taxi with a service to light a car?

Another way out of the situation, but, of course, it works exclusively in large cities - a taxi with a car lighting service, as well as a taxi whose driver will help, if necessary, tow the car to the right place, as well as provide minor repairs. Such services in Russian Federation There are a lot of both taxi services and online platforms where you can urgently order a service. What to choose is up to you.

Video: How to Light a Car?

The owner of the car needs to be prepared for any surprise. If the car does not start due to a dead battery, you will need help from external source energy. Get a charge from the battery of another car in professional slang is called "light up". To perform the operation, you need to know how to properly “light up” the car. What do you need to use the donor's help, what tools 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”, use your car as a donor. If you have new battery fully charged, the car works, there is some free time, it is unethical to refuse help. Batteries must be of similar capacity and voltage, donor machine of the same or higher class.

“Lighting up” another car from your car is harmful and dangerous if the operation is carried out as follows:

• during the “lighting up” of the car, the donor stands with the engine running;
• in the process of "lighting" on the auto acceptor, the ignition is on and electrical appliances are turned on;
• the donor is a smaller capacity battery;
• the sequence of operations during assembly and removal of connecting wires is violated;
• small-section wires with poor-quality insulation, faulty contacts or "crocodiles" are used;
• security measures are not followed.

If you perform the operations correctly, there will be no harm to the battery and on-board network of another car. You can not "light" from the old battery. You should refuse the donor service if its battery is leaking, an acid smell is felt.

How to "light up" a car

The modern car has a complex electronic stuffing, requiring the stability of electrical parameters. Experts and practitioners have developed an algorithm for how to safely “light up” one car from another. The sequence of assembling the circuit and removing the wires is important when lighting up from the donor car. During the recharging period, a current of 300-400 A passes through the circuit, the created short circuit can bring a lot of trouble.

How to “light up” your battery from another car? First of all, you need to get connecting wires good quality, for smoking. Let them always be in the trunk. Included is a black wire for connecting to minus or ground, red - positive. The wires are massive, their cross section is at least 16 squares. Both ends have crocodile clips. If you choose thinner cables, you can get burned from extreme heat and even a fire. In Chinese products, often thin wires are hidden under thick insulation.

When choosing a car for “lighting up”, make sure that it has a good battery, equal to or larger capacity, but with one output voltage. Before "lighting" your battery, check its serviceability. Do not recharge if the battery is frozen in ice or leaking.

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

Signs of a bad battery:

• when turning the ignition key, straining sounds are heard;
• the indicators on the control panel are not lit or are dimly lit;
• Uncharacteristic sounds are heard under the hood.

To “light up” the car’s battery, you need to install it in an open place, with the possibility of access for another car. The car used as a donor must work on XX so that its battery is as charged as possible.

look practical lesson on the video, how to “light up” the battery.

How to “light up” a car from another car with wires

So you picked suitable vehicle, put it conveniently to “light it up” with wires. He has already worked, recharging the battery. How to properly assemble a scheme for transfer from a donor?

1. On both vehicles, turn off the ignition and all on-board electrical consumers.
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 housing, in a place where there is no paint, to ground.
3. The donor engine starts, the battery is recharged for 5-7 minutes. How much to “light up” depends on the air temperature.

After recharging, the donor is completely jammed, the wires are removed and the recipient's car is tested. 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 fine, but the car won't start.

In the case when there was not enough charge, you should re-light the car for 10 minutes, according to the same scheme. If there is no result, technical assistance should be called. Reason: faults are not in the battery.

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

How to “light up” a car from another car, we suggest watching a video.

How to “light up” a car from another automatic machine

Let's figure out whether it is possible to “light up” a car on an automatic machine, use another automatic machine as a donor? What's the Difference? Systems electronic control designed for constant pressure. If the battery has become completely unusable, after replacing it, a reconfiguration of the computer is required. Is it possible to recharge a dead battery in place from another car with a machine gun and how to give, “light up” another car?

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

When connecting the wires with which you need to “light up” the machine, you must observe the connection sequence and polarity. If the terminals are mixed up, a short circuit will occur with bad consequences.

"Smoke" the car correctly automatic:

• Remove the key from the ignition and leave the door open. (When power is supplied, the machine will howl and door lock will be blocked). Set both machines to the parking brake. The auto donor must be warmed up by running the engine at idle for more than 5 minutes.
• Connect the positive wire first, 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 lighters”, you must turn on the resistance on your car to smooth out the power surge. Do not turn on the lighting lamps - they may burn out. You can turn on the heated glass.
• Remove the wires first from the negative terminals, then from the plus.

So you can “light up” 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” from a working donor machine. Is it possible to "light up" from a running car? If the donor battery works with an open circuit, it does not power onboard networks, no power surge will occur. When the engine is running, only the battery will be charged, which discharges the charge, “lighting up” the dead battery. But by the time the driver makes a test run, the donor car must be muffled. Otherwise, a power surge may occur, failure of expensive equipment.

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

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

How many cases when you need to “light up” the car, but the circumstances of the help change, the sequence of some operations. Much depends on the type of car - diesel or gasoline, automatic or mechanic. At experienced drivers there is a well-established scheme on how to properly “light up” your car from another, which donor is suitable and which is not.

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

The most common way to properly “light up” a dead car from another running one. It is necessary to start the donor engine for the time required to recharge the dead battery. It can be from 5 to 20 minutes. Shut off the correct car. Remove the wires and do a test run. You may need to warm up the car a little more, still “light up” the car with a dead battery if the starter spins lazily. As soon as the engine is started, the generator will start charging the battery, after 10-15 minutes you can go.

Another method is designed for experienced drivers with a conventional manual transmission, a minimum of electronics. The wires are connected. How to properly and quickly give a "light" car to the owner with a new battery? Run the donor motor for 5-6 minutes. Try to start faulty car. The start attempt does not exceed 15 seconds, the interval is one minute. As soon as the engine starts, leave both cars turned on and tied 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 power surge.

“Lighting up” is an undesirable, emergency and dangerous operation. Is it possible to “light up” from a car if the driver of the donor has doubts about the health of the battery? The owner's fears are justified:

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

How to properly “light up” a car from another car, look at the video.

How long is it reasonable to “light up” the car

The “lighting up” method resuscitates 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, temperature environment. As a rule, “lighting up” a car from another car, assembling the circuit and removing the equipment, takes about 30 minutes. A second operation may take the same amount of time. A person who is in a hurry on business should take this circumstance into account.

How to "light" a car from another battery

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

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

Booster can "light up" not only car battery, they charge electronic gadgets when the network is not available. But its cost is high. Basically, such portable compact chargers are used to “light up” a car in the case when the battery loses its charge and capacity in long journeys. Special starting chargers are compact, they serve to “light up” a car from another battery. Assembly correct scheme power supply from an external source is relevant, this is the same “lighting up” from an external battery.

The main problem with using external energy storage devices is their ability to produce only a few launches. But there are professional boosters that work from the network. But in case of force majeure, “light up” the car from external battery- the rescue.

We did not have time to look back, and winter, as the classic wrote, is again looking into the eyes. The time of snowdrifts, rubber and discharged batteries begins. For those whose battery has weakened over the summer, winter quickly shows that it was necessary to change earlier. This happens, according to the law of meanness, usually in cases where you urgently need to get somewhere. There is only one way to quickly solve the problem in such a situation - to “light it up” from another car.

But it’s better not to renounce the battery as if it were a bag or a prison, even if you constantly monitor its health: you forgot to turn off the headlights, the alarm turned off, or you just drove away for a long time, and the car stood motionless - and now you are running around the yard in search of someone who would " lit a cigarette." For those who have never done this procedure, we have prepared material on how to "light up" correctly.

Training

In theory, you can light a cigarette from any car, but in practice it is highly desirable that it be from a donor (so, in order not to get confused, we will call the one who “lights up”) battery capacity was not less than the recipient(to whom they "light up"). Do not "light up" from a small car big jeep, but from a machine with a conventional gasoline engine– . There is a possibility that it will work, but this is an inadequate risk. It goes without saying that you can “light up” only from cars that have the same battery voltage, that is, trucks for cars will not work.

Even if you managed to find a car of a suitable weight category, it is better to ask the owner about the well-being of his battery, if he is old and has already failed, then it is better to look for another option, otherwise you will have to “light up” two cars.

There is a stereotype that machines with complex electronics cannot safely act as a donor for themselves. Actually it is not. If during the “lighting up” the engine is turned off and the ignition is turned off, then the voltage drop is not terrible for the on-board electronics, because it is not working at that moment.

Starter wires. Red terminal - plus, black - minus

The fact that wires are needed for “lighting up” goes without saying. Any two thick wires of the required length will fit, but special lighting kits with “crocodiles” at the ends are much more convenient, especially if this is not a craft from China, but a more or less high-quality thing - with thick wires and reliable “crocodiles”.

Connection

It is necessary to fit the two cars as close as possible to each other (but, of course, not so that they touch). If the donor also stood for a long time without recharging the battery, then you can let it work for 5-7 minutes at medium speed in order to better recharge its own battery. If the donor has traveled a lot before, you can not do this.

We connect the wires. Doing this is recommended starting with the "plus", first on the donor's machine, then on the recipient's machine. Then we connect the "minus". The donor needs to be connected to the negative output of the battery, and the recipient can be "finished" to the mass of the body. It is believed that this is somewhat safer than connecting to the negative output of a discharged battery.

Why in this order? From an electrical point of view, there is no difference, but it is much safer this way. If you connect the “minuses” first, and then accidentally drop the “positive” wire on the body, then a short circuit cannot be avoided. But if you drop the “minus” with the “plus” connected, the consequences will not be so severe. Unless, of course, you hit the terminal directly.

Next in the list of priorities is the controversial item - whether to start the donor engine when the wires are already connected. On the one hand, this will help to cheer up the dead battery, the current through the wires from the operating system will recharge the recipient's battery, it will be easier for him to start the engine later. Sometimes they light up only in this way - they let the donor work longer, charging the recipient's battery, and then disconnect the wires.

It is not necessary to start the donor engine

But in such a situation there is a risk, because it is not known for certain why the recipient's battery has run out, and what if he "short" or has another malfunction. Connecting an untested unit to the vehicle's electrical system can lead to unpredictable problems.

It is up to you to start or not to start, but in general, this item is not necessary to start the recipient's engine: if the donor battery is in good condition, its reserve is enough to start someone else's car. If you decide to start, then you need to make sure that at the moment when the recipient tries to start the engine, the motor, the ignition and all the electronics of the donor were turned off.

Shutdown

If everything worked out, you need to give the recipient car 5-10 minutes so that its battery gains the necessary charge for the next start. Then turn off the engine and start dismantling the wires. It is carried out in the reverse order from the installation - "minus" the recipient, "minus" the donor, "plus" the recipient, "plus" the donor.

Possible mistakes

Separately, we will consider several potential opportunities to "screw up" when lighting up. There are not very many of them, but each can be expensive.

1. Start the recipient engine while the donor engine is running. At start-up, the voltage in the network drops, it is impossible to predict whether the donor relay-regulator can digest it and how the computer will behave. If you don't want to do it later expensive repairs– turn off the engine and turn off all electronics that may suffer from a voltage drop.

2. Disconnect the wire terminals when the engine is running. Many underestimate the danger of this step. Of course, the risk here is much less than in the first paragraph, but it is still there, because we disable additional element, a drop is possible. In addition, in this situation, there is a risk of dropping the “positive” terminal on the body, which also will not end in anything good.

3. Reverse polarity when connecting. This is really an epic fail, if you don’t want to see fireworks from sparks, you don’t need to confuse “plus” and “minus”. Terminals are specially made of different diameters, "crocodiles" are made with this in mind. If something does not fit - this is a reason to be wary and check.

If done correctly: use good wires, pick up an adequate car, connect everything according to the instructions and not make mistakes - then “lighting up” is not dangerous. The main part of the stories about breakdowns after lighting is connected precisely with the miscalculations of the drivers, and not with the operation in principle. If you know the sequence and all the pitfalls, then you don’t need to be afraid of “lighting up” - no matter which side of the wires you are on.
