Electrical circuit of the “four” - features

First of all, it is worth noting one point. The electrical circuit of the VAZ-2104 car is single-wire. This solution provided the required simplicity. Here, all elements are connected to each other by one “positive” wire. In turn, the designers assigned the role of “minus” to the metal parts of the car - the body, transmission, engine.

The devices included in the Quartet’s electrical equipment can be divided into the following groups:

• working equipment - it is responsible for starting and normal operation of the engine;
• auxiliary – facilitates the process of operating the car;
• light and sound alarm;
• increasing comfort.

Let's look at them in a little more detail. The first group includes elements of the ignition system. This also includes the generator, starter, battery and devices that control all these parts, with the exception, of course, of the battery.

After the engine is started, the functions of the battery are taken over by the generator. It generates the electrical energy necessary to operate devices. In addition, the generator is also responsible for replenishing the charge lost by the battery.

The VAZ-2104 was produced in several modifications, including diesel and injection gasoline engines. However, in general, the electrical equipment of all of them is approximately the same, with minor distinctive features. Let's give some average option.

In the Quartet, as well as in other cars, all electrical equipment is connected to each other using wires of different colors. This point is also shown in the diagram. However, the problem is that many VAZ-2104s today are quite old. Accordingly, during operation they were repaired, and more than once. Often, owners who changed the wiring cared about its color, saying that it fits the parameters - and that’s good. However, this subsequently makes it difficult for inexperienced motorists to read the diagram. Therefore, if you are doing repairs on your own, be sure to take this point into account.

Difficulties with repairing the electrical equipment of the Quartet can arise even for experienced car enthusiasts. Quite often the problems are related to the wiring replaced by the previous owner. A new car owner sometimes has to spend quite a lot of time trying to figure out what’s what. Well, the most unpleasant situation is when the previous owner began to change the wiring, but never completed the job. In such a situation, as they say, the devil himself will break his leg. Often, in order to find out where a particular wire goes, you need to spend several hours.

Experienced car enthusiasts recommend in such cases not to understand the unsuccessful undertaking, but to simply replace all the wiring. This will require significantly less time and effort, while we are not talking about any significant material costs here. But the newly laid wiring will fully correspond to the diagram. Accordingly, the next time a malfunction occurs, you can easily find the cause and be able to quickly eliminate it.

Here you just need to take into account a few important points. Firstly, all wires must be of the correct cross-section. Otherwise, problems with the operation of electrical equipment may occur. Secondly, you are doing this work, as they say, for yourself - which means the color of the wires in your car must exactly match those indicated on the diagram. As you can see, there is nothing particularly complicated here. But by replacing all the wiring, you save yourself for a certain period from the need to repair this component of the electrical equipment system.

Of course, devices will fail - the older the car, the more often this happens. But at the same time, you will clearly understand which wire leads where. This allows you to significantly reduce the time spent both on finding the cause and eliminating the malfunction. This is a very important point if all the work is done independently. In addition, re-installed wiring will greatly facilitate the process of installing some new equipment. Often, owners of “fours” of earlier releases install an electronic ignition instead of the stock contact ignition. Another possible option for modernizing a car is replacing the carburetor with an injector.

Signs of electrical circuit malfunction

The electrical wiring of the VAZ 2104 is a weak point; something is constantly not working. Since the production of cars of this model was discontinued many years ago, VAZ car owners with a carburetor or injector are often faced with the problem of equipment failure. If electrical equipment begins to work incorrectly, the motorist needs to diagnose the circuit. Always remember that when carrying out electrical wiring repair work, the system must always be de-energized. Checking the functionality of certain devices is carried out based on studying the circuit.

Fuse block "four"

If you notice that there are problems with the electrical circuit, the vehicle may operate in one of two states:

1. If the car cannot move and does not even start, then in general there are many possible reasons why this happens. In such cases, the first thing to do is diagnose the performance of the distributor and starter; it is also necessary to check the battery charge. In the winter season, owners of “fours” with old batteries often encounter a similar problem as a result of the battery being completely discharged. As practice shows, complete failure of the generator occurs much less frequently, but the functionality of this device also needs to be checked.
2. The car can start and even drives, but there are malfunctions in the operation of the equipment. Problems can also be very diverse - short circuits, breaks, fuse failure, and breakdown of the equipment itself. It would seem, why don’t the turn signals, windshield wipers, and rear view heating work at the same time? At first glance, these elements are in no way connected with each other, but it is worth remembering that they all work when the ignition is turned on, and everything falls into place.

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

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

Electric windows

Some car owners install electric windows on their VAZ 2104.

The connection diagram for Forward electric windows in the front doors of a VAZ 2104 is quite simple

The features of installing such window lifters on a VAZ 2104 are determined by the size and design of the front door windows. Unlike other classic VAZ models, the front doors of the four (like the VAZ 2105 and 2107) do not have rotary windows. Fully lowered front windows take up more space inside the door frame.

When choosing electric window regulators, you should ensure that there is free space for installing the electric motor and drive mechanism.

Video: installation of “Granat” window lifters on a VAZ 2107

Thus, independent repair of electrical equipment of a VAZ 2104 for an inexperienced car owner is usually limited to replacing fuses, relays and warning lights, as well as searching for broken electrical wiring. It is quite simple to do this, having in front of your eyes the wiring diagrams for electrical appliances.

VAZ 2104 car platform

At first, the VAZ 2102, which was an “extended” version of the classic “penny”, was assembled as a universal model with increased capacity in factory buildings. However, having identified a number of design flaws, the engineers decided to use a different platform for the station wagon.

At its core, the VAZ 2104:

1. It was an extended modification of the VAZ 2105;
2. Most of the parts were unified with the entire model range of the Zhiguli family;
3. The rear of the car received a full-size door equipped with heated glass and a windshield wiper;
4. An additional center console with function keys has appeared in the cabin.

For reference: The factory instructions offered for the new car did not always reflect the changes made during the production and modernization of the VAZ 2104.

Basic and auxiliary elements General

electrical circuit diagram VAZ 2104 is Everything. single-wire electrical equipment in a vehicle is connected to each other through one cable - quality. The positive negative contact uses earth grounding “or”, that is, the car body. Components of a car - engine, transmission - can be used.

electrical equipment Everything connected via wires can be divided into several groups:

1. Working devices. With their help, the starting and functioning of the machine's engine is ensured.
2. Light and sound alarm.
3. Assistive devices. These devices make the vehicle easier to use as a whole.
4. Support equipment for more comfortable control.

Working devices should include:

• battery;
• generator components;
• ignition system unit;
• devices through which these units are controlled.

The battery in the VAZ 2104 is one of the main elements; it can be attributed to all groups of components. Batteries are used to power electrical appliances when the power unit is turned off. But the main task of the device is to provide power to the starter mechanism. The latter is a power electric motor, through which the unit and ignition system are started. If the engine is started, the generator set takes over the functions of the battery.

This node generates electricity, which is necessary to power the entire equipment. At increased crankshaft speeds, the generator restores the battery charge that was spent on starting the internal combustion engine. If the load on the equipment is too high, when many devices are turned on, the generator unit may not cope with its task. The battery helps him, providing power, since an overload of the power grid will lead to a breakdown of the generator.

The ignition system in a car is used to form a spark charge in the cylinders of the power unit. This combustion is promoted by the combustible mixture. The voltage value in the on-board vehicle network is 12 volts.

This system includes:

• ignition coil;
• distribution or distributor assembly;
• spark plug;
• high voltage lock;
• wires are the main component that allows you to direct the starter mechanism and the ignition system to energy when the light is on.

The start-up alarm is designed to illuminate the road surface at night; for this, low-beam optics and high beam are used. Using flashlights, you can warn other road users about the maneuvers the driver plans to make.

Overtaking is about:

• goes;
• turns;
• braking;
• driving backwards For.

In the course of designating dimensions, individual qualities are used. The horn headlights use a steering light. The alarm horn also includes the interior lamp in the vehicle lighting. All battery equipment is powered from the engine when the engine is off and from the generator when it is running.

Carburetor internal combustion engine

Most classic VAZ models with a carburetor are equipped with a KSZ contact ignition system. Since 1987, cars began to be equipped with a contactless ignition system. The engine for the VAZ 2104 was created on the basis of the VAZ 2103 power unit, and accordingly, the VAZ 2103 electrical circuit was used.

Classic ignition

The KSZ includes a distributor (2), a coil (5), spark plugs (1), high-voltage wires, and connecting wires. The system also includes a capacitor (3), a relay (7), a breaker cam (4), a mounting block (6), and a switch (8).

On machines with KSZ, a distributor 30.3706-01 is installed. It is located on the left side of the cylinder block in the front part. Thanks to it, the circuit of the primary winding is interrupted and high voltage is distributed across the spark plugs in the required sequence. The distributor consists of ignition timing regulators, a high-voltage pulse distributor, and a breaker with contacts.

A B-117A with an open magnetic circuit is used as an ignition coil. It is located in the engine compartment and is attached to the left mudguard using two nuts. The device is used to convert low-voltage current into high-voltage current. The installed A17DVR spark plugs serve to ignite the fuel-air mixture in the cylinders of the power unit.

A VK347 type switch is installed, which has an anti-theft device. The anti-theft operating principle: when the key is removed from the lock in the “Parking” position, the locking rod extends, which blocks the steering shaft, entering a special groove.

Electronic ignition

The design of the contactless ignition system includes:

• distributor (distributor);
• sensor;
• switch that controls the system;
• high voltage coil;
• spark plug ;
• connecting and high-voltage wires.

On VAZs with BSZ, a distributor 38.3706-01 is installed, its location coincides with the KSZ distributor. The coil consists of two windings. One is connected to the ignition switch relay, and the second is connected through a high-voltage wire to the distributor.

Using small cross-section wires, the coil and distributor are connected to a switch, which is responsible for the timely supply of a spark. The commutator converts the sensor pulses into a pulse current, which is supplied to the primary winding of the coil. The coil is also located in the engine compartment, like the KSZ coil.

Do not disconnect the wires from the switch if the ignition is on. The switch may be damaged if the battery terminals are removed while the engine is running.

Total information

The appearance of the VAZ 2104 station wagon on the domestic market was justified by several reasons:

• Firstly, its predecessor, the VAZ 2102, was based on a penny chassis, while the automaker was already mass-producing more modern models (see, for example, VAZ 21213: nuances of operation).
• And secondly, the country needed transport that would allow ordinary citizens to provide themselves with a universal vehicle that could be used to transport simple belongings over long distances.

The video presented in the article clearly demonstrates its capabilities as a multifunctional vehicle capable of not only transporting passengers within the city, but also as a means of active tourism:

1. travel to mountainous areas;
2. trips to nature;
3. long-distance routes to sea coasts, etc.

The model turned out to be popular in the countries of the socialist camp.

It was supplied there from 1984 to 2009 inclusive, and was offered under the trade names:

• Lada Estate,
• Lada Combi or Lada Nova Combi,
• Lada Riva Break.

Export versions have always been distinguished by high-quality painting.
Please note! The electrical wiring diagram of the VAZ 2104 in the export version was distinguished by the presence of a heated rear window and a windshield wiper on the rear door. Also, similar equipment was found in the VAZ 21043, which borrowed the interior and electrical equipment from the VAZ-2107, and since 1994 it has become standard equipment for all “fours”

Models for the domestic market

Before the appearance of the VAZ-21047 modification, the car was produced in a standard configuration, which allowed car owners to service it with their own hands. And many systems were quite familiar to car owners from other models of the domestic automobile industry.

Classic power supply system VAZ 2104

The Tolyatti Automobile Plant made no secret of the fact that the model was almost completely unified with the VAZ 2105, because even the factory instructions were issued the same for the two models.

There are no secrets: the “four” is an extended “five”

But with the advent of injection technologies in the VAZ production program, the VAZ 2104 wiring diagram for the injector was modified.

In particular, the Quartet received:

• five-speed gearbox;
• electrical equipment and interior of the VAZ-2107;
• power unit and new electronic units that controlled its operation.

VAZ 21047 borrowed equipment and components from the seventh model

Electrical wiring of VAZ 2104: differences between modifications

The automakers coped with the task of producing a successor to the famous VAZ “two” without any problems - the “four” inherited almost all the elements and components from the donor VAZ 2105. Such unification made it possible to quickly launch a new model into series, so even the electrical wiring of the VAZ 2104 did not have significant differences. But with the advent of modifications, differences still appeared.

The dream of any summer resident of the 80s - the VAZ 2104 with a powerful engine and large capacity is capable of much.

VAZ 21047 borrowed equipment and components from the seventh model

For reference: According to the factory classification, models with an injection engine were called VAZ-21041i or VAZ-21041 VF, but in the automotive environment they were often called “four-seven”, “forty-seven” or more officially VAZ 21047.

Summary

Overall, the car turned out to be of good quality, which allowed it to remain on the factory assembly line until 2012. Among the features of this attractiveness are low price, the possibility of increasing the interior, ease of maintenance and availability of spare parts.

Replacement of electrical wiring of VAZ 2104

If there are failures in the power supply system to the devices, you need to ensure the integrity of the power line.

To do this you should:

1. De-energize the area being diagnosed. When checking the wiring, be sure to disconnect the battery or the fuse for a specific section of the line.
2. Connect the contact elements of the multimeter to the ends of the circuit being diagnosed. The second probe is connected to the ground or ground of the vehicle.
3. Check the integrity of the wires. If there are no readings on the tester display, this indicates a break in the line.
4. Replace the electrical circuit with a new one.

The selection of cables for replacement is carried out in accordance with the characteristics of the equipment and power supply circuit. It is necessary to use only standard conductors or cables from other similar models with similar characteristics. To replace the wiring, the front or rear part of the cabin is disassembled. If the cable length is insufficient, you will have to extend it yourself, and solder and insulate all connections.
