The work of any electrical equipment in the car is directly related to the performance of the wiring. If there are clips in the chain, it can affect the functionality of the equipment as a whole. From this article you can find out what is a VAZ 21043 carburetor with a detailed description of the elements.

[Hide]

What is included in the power supply?

Diagram of VAZ 2103 or 21041, regardless of the ignition system used, includes the following elements:

• battery, minus the output of which is connected to the body;
• starter;
• regulator relay;
• BP is a block with fuses designed to protect equipment from short circuits and high voltage;
• generator, which is one of the main components of VAZ wiring;
• ignition switch.

On any car VAZ minority outputs from energy consumers are derived for mass, namely, on the car body. The body itself is an excellent conductor. But about the wired compound, it should be borne in mind that it is provided only by the positive wiring. The above is the VAZ 2104 and VAZ 2103 scheme with all the electrical caps and the designation of all items, and the table is located below, which indicates the purpose of all relays.

Signs of disability of electric hammers

Wiring VAZ 2104 is a weak point, constantly something does not work.Since the production of cars of this model was discontinued many years ago, often carbustners of a VAZ with a carburetor or an injector face the problem of non-working equipment. If electrical equipment has become incorrect, the motorist needs to be diagnosed with the scheme. Always remember that when repairing electrical wiring work, the system must always be de-energized. Checking the performance of certain devices is carried out on the basis of the study of the scheme.

If you have noticed that malfunctions appeared in the work of electrocups, the vehicle can work in one of two states:

1. If the car can not move from the scene and does not even start, then in general, there are many possible reasons for which this is a lot. In such cases, primarily diagnoses the performance of the traver and starter, it is also necessary to check the charge of the battery. In the winter season, the owners of the "four" with old batteries often face a similar problem as a result of a complete discharge of AKB. As practice shows, the full failure of the generator happens much less frequently, but the performance of this device must also be checked.
2. The car can get started and even rides, but there are failures in the equipment. Problems may also be the most diverse - both short circuits, and cliffs, and failure of the fuse, and breakage of the equipment itself. It would seem why at the same time not, wipers cleaning windshield, heating of the rear view? At first glance, these elements are in no way interconnected, but it is worth remembering that they all work when the ignition is turned on, and everything becomes in place.

According to experts in the field of wiring repair, the first thing to do is check the ignition switch device, since this component is intended for:

• controls to all the functionality of the ignition system;
• vehicle alarm management (video author - Edward Deviatkin).

Diagnostics of faults

So, if you want to check the performance of all elements of the electrical wiring diagram, you must follow certain actions. If there are problems in the equipment, first of all it is necessary to check whether the fuses installed in the block are necessary. If everything is in order with the fuses, and does not work, for example, optics, you will need to check the lamps. If everything is normal with them, the wiring transversion is performed using the tester.

In the event that the machine does not start at all, you will need to perform the following actions:

1. First, check the battery, as mentioned above, the full discharge may cause the engine to start the inability.
2. If the battery is charged, you need to ring the chain section from the ignition coil to the generator. It often happens such that the wines of the entire cliffs. When snapshots in the electrical wiring scheme, it is necessary to replace the wires. If you have noticed that there are oxidations on contact contacts, they need to be eliminated. For this, contacts either change or cleaned.
3. If the coil does not give a spark, the motor will not work. To check if there is a spark, pull out the high-voltage wire and bring it to the mass, that is, to the gland (body, for example). Your assistant at this moment should turn the starter to run the engine. At the time of trying to start between the wire and the mass should fire spark.
4. Engine Troy and the impossibility of its launch is often associated with the exploitation of bad spark plugs. Prevent the normal operation of the power unit can Nagar and the flare, which appears on the electrodes. Accordingly, with a too large layer of plaque, the appearance of the spark is impossible. To solve the problem, it is necessary to clean the candles, detailed instructions you.

In the early 80s, with the aim of replacing the VAZ-2102 universal, the Volzhsky Automobile Plant specialists began to design a new car. Before the designers there was a task to create a new wagon with minimal cost and maximum effect. As the basis of the car, the VAZ-2104 sedan was taken, which was to remake. As a result, in the second half of 1984, a new station wagon "VAZ" with the factory index of the VAZ-2104 appeared on the world or in a simple "four".

The VAZ-2104 wagon was completed with various engines, including the VAZ-341 diesel engine. Over time, after another modernization, the car received a 5-speed gearbox.

Compared with the previous wagon VAZ-2104 had a number of advantages and by 1985, the "Two" was completely outlined from production, thus the next 15 years of the car was the only universal of Togliatti production up to the appearance of VAZ-2111. In 2003, AvtoVAZ ceased to issue VAZ-2105 universal, but from the same moment until 2012 its production continued Izhevsk automotive factory.

Design and design

Compared to the VAZ-2105 sedan, on the basis of which the VAZ-2104 was created, the universal received a less hard body. After lengthening the roof to enhance the stiffness, there were emptyings, but the obtained stiffness was not enough and in order not to wash the roof to heat the trunk located on it was not recommended. In the rear of the car to access the trunk, the door opens the door, the glass of which, unlike the previous station wagon, was heated and wiper.

The wagon salon VAZ-2104 was exactly the same as the VAZ-2105 sedan, with the exception of the rear seats, which, as it believes the universal needs to be folded, thereby increasing the volume of the luggage compartment. The default trunk volume was 375 liters, and when the seats are folded, it increased to 1340 liters. Thereby allowing carrying large loads weighing up to 455 kilograms. Of the disadvantages, it can be noted that the standard heater from the sedan was much more difficult in the cold season to warm the significantly enlarged salon.

As a power unit, the VAZ-2105 wagon was installed exactly the same engines with a volume of 1290 to 1689 cm3 and with a capacity of 64 to 84 horsepower. But, despite the fact that the engines were the same, the versatile speed was lower (137 km / h instead of 143) due to the less streamlined shape of the back. Since 1999, Melkossorino has modified the wagon with the factory index of the VAZ-21045D, which was completed with a 1.52 liter VAZ-341 diesel engine and a capacity of 50 horsepower. The diesel wagon was much more expensive, but if you consider that at that time, diesel fuel was much cheaper than gasoline, then the operation of this modification was cheaper.

VAZ 2104 with rear-wheel drive and Body "Universal" was produced from 1982 to 2012. The model was constantly improved: electrical equipment was changed, the fuel injection system, a five-speed gearbox and semi-sending front seats appeared. The modification of the VAZ 21043 was supplemented with the cleaning system and heating the rear door window. The power supply system of individual assemblies of the car is quite simple.

Cumulative electricity supply schemes VAZ 2104

All electricity consuming VAZ 2104 systems are switched over a single-wire line. Electricity sources are battery and generator. The positive contact of these sources is associated with electrical devices, and the negative goes to the body (mass).

Electrical equipment VAZ 2104 is divided into three types:

• work equipment (battery, generator, ignition, starter);
• auxiliary operational equipment;
• light alarm.

When the engine is turned off, all electrical equipment, including the starter, is powered by the battery. After starting the engine starter, the generator becomes the source of electricity. At the same time, it restores the battery charge. The ignition system creates a spark discharge to ignite the fuel mixture entering the fuel engine. The lighting function includes external lighting, interior lighting, inclusion of dimensions, sound signal. The switching of electrical circuits occurs through the ignition lock consisting of an electrical contact node and a mechanical anti-theft device.

The VAZ 2104 uses a 6T-55P battery or similar. As a source of alternating current, a synchronous generator 37.3701 (or M-222) is used. This is a three-phase generator with electromagnetic excitation and a built-in straightening unit on silicon diodes. The voltage removed from these diodes feeds the rotor winding and is supplied to the battery charge control lamp. On vehicles with generator 2105-3701010, this lamp is not involved, and the battery level is controlled by a voltmeter. The generator is attached to the brackets in the right (in the course of the movement) of the front of the engine compartment. The generator rotor is driven by the crankshaft pulley. Starter 35.3708 is attached to the clutch videoer on the right side of the engine, is protected by the heat-insulating shield from the exhaust pipe pipe and turns on the electromagnetic remote control relay.

The VAZ 2104 uses contact, and in cars produced after 1987, a non-contact ignition system. The contact system contains the following items:

• the breaker dispenser designed to open the ignition coil circuit with a low voltage current and the high voltage pulse distribution of the ignition candles;
• the ignition coil, the main function of which is to convert the current of the low voltage in the high voltage current;
• spark plug;
• high voltage wires;
• ignition switch.

The contactless system consists of:

• the sensor-dispenser feeding the low voltage control pulses to the switch and the high voltage distribution pulses on the ignition candles;
• switch intended for interrupting current in the low voltage chain of the ignition coil in accordance with the signals of the distributor sensor;
• ignition coils;
• spark plugs;
• high voltage wires.

The current is constantly being served in electrical outlines:

• sound signals;
• stop signals;
• cigarette lighter;
• interior lighting;
• portable lamp sockets;
• emergency light alarm.

To switch and protect the electrical appliances from voltage drops in a special niche of the subcapor space, there is a mounting unit with fuses and a relay, the purpose of which is schematically indicated on the block lid.

Electric windows

Some car owners are installed on their VAZ 2104 electrical windows.

The features of the installation of such windows on the VAZ 2104 is determined by the size and design of the windows of the front doors. Unlike other classic VAZ models in the front doors of the fourth (as well as in the VAZ 2105 and 2107) there are no rotary vents. Fully lowered front windows occupy more space inside the door housing.

Thus, the independent repair of electrical equipment VAZ 2104 for an inexperienced car owner is usually limited to the replacement of fuses, relays and signal lamps, as well as search for electrical wiring. Make it, having the electrical appliances connecting the circuit before the eyes, is quite simple.

This resonator is installed on the VAZ 2104, 2106, 2107 Izhevsk assembly with an injection motor and Euro-3 standards.

How to understand which resonator is installed on your car and distinguish one of the other?

As a rule, Euro-2 resonators were installed on cars manufactured until 2008. In 2008, Euro-3 resonators began to be installed. But this information cannot be 100% of this information, so we will tell you how to visually distinguish the resonators of Euro-2 from Euro-3 by car VAZ 2104 assembly of the IZH car.

If you put these 2 resonators nearby, it will be seen that Euro-3 shorter euro-2 for several centimeters. But if your frightened resonator still stands on the car and compare it with nothing to understand which of the 2nd you choose a look at the catalyst, it is a neutralizer of exhaust gases, to which the resonator is screwed (in the picture, the catalysts are replaced by inserts).


If you see a catalyst in which the oxygen sensor is screwed and there is a flange under 3 mounting bolts from one of its sides, which means you need a resonator Euro-3. If you see a catalyst, from both sides there is an flange under 2 bolts and the oxygen sensor does not screw in it, which means you need a resonator Euro-2.
