Fundamental differences in the design of the fuse box depending on the Gazelle model

This is what the new fuse box looks like

The design differences of the modification of the Gazelle class, based on various electrical equipment protection systems, can be divided into the following main groups and their features can be highlighted. Watch the video on how to install a new fuse box.

Cars with carburetor-type gasoline engines

1. Cars produced before 2003:
   equipped with old-style electrical fuse modules with cylindrical type fuses with a nominal value of 8 and 16A;
2. control relays are installed separately from the mounting block;
3. the engine compartment block (BPR-2) has power fuses of 40A for the light circuit and 60A for the general plus.

4. Models 2003-2010:
   new-style units with plastic fuses with protection thresholds of 5, 10, 15, 20 and 25A were installed, depending on the equipment;
5. control relays are also located independently of the unit;
6. the power protection module can be different: BPR-2 with protection of 90A for the light and generator circuits and 60A for the general plus.

7. BPR-4 for cars with a pre-installed anti-lock braking system and additional 25 and 40 A electrical fuses.

Cars with gasoline injection engines

1. The main fuses of plastic type 25, 10, 15, 20 and 5A for various circuits are combined into a single mounting module located in the cab.
2. The main control relays are included in the unit.

Installation process of protective relays

Diesel vehicles

1. A main safety module is installed, similar to fuel-injected cars, with additional 5A electrical fuses for the engine management system.
2. Modified engine compartment, including protected circuits:
   air heating system with 125A protection;

Diagram with car fuse sizes

The variety of factory configurations of Gazelle cars, both in terms of the pre-installed engine and additional equipment, and the multiplicity of their combinations leads, in turn, to differences in the electrical protection system and the design of the mounting block.

Thus, the Gazelle fuse box is a mandatory element of the protective mechanism of the vehicle’s electrical equipment and is implemented taking into account the design features of a specific modification of the vehicle.

The two-level construction of the safety circuit provides reliable protection of on-board devices, both from a short circuit in the machine network and from voltage surges, thereby ensuring their trouble-free operation.

Possible wiring faults

What malfunctions in the wiring of a GAZ 31105 with a Chrysler engine, GAZ 31029 or any other model can occur:

1. Lack of contact. Such a malfunction may be associated with a break in the electrical wiring, oxidation of the outputs, or their burning. If the contact is oxidized, then it needs to be cleaned, if the wire is broken, then it must be restored, if the reason lies in burning, then first you need to eliminate the problem of overvoltage. It is quite possible that the connector simply came out of the socket; this often happens when the plug is poorly secured and constantly driving on uneven roads.
2. Battery discharge. This problem most often occurs in the cold season - in the cold, batteries are most susceptible to discharge. If this happens during the warm season, then you need to check the battery charge, the level and density of the electrolyte, as well as the case for damage.
3. Circuit break. A malfunction of this type is diagnosed by searching for the damaged area manually or using a tester. The break must be eliminated by replacing the wire, and the replaced wire should also be wrapped with electrical tape - this will create an additional layer of insulation. When laying wires, make sure that they are not exposed to moving mechanisms, otherwise this will lead to another insulation breakdown and breakage.
4. Burnout of the safety element. This problem is most relevant for cars that have power surges in their on-board network. If the voltage surges are noticeable, then the fuse simply will not be able to withstand the load, which will lead to its failure.

The fuel pump does not pump: causes and diagnostics

Let's start with the fact that if the gas tank is full, the battery is charged, the spark plugs are dry and there is a spark, the starter turns the engine normally, but the engine does not seize, then you should pay attention to the gas pump. A common problem is that there is no power to the fuel pump after the ignition is turned on. In a similar way, the malfunction manifests itself in motion, when the power to the fuel pump is lost and the engine suddenly stalls.

An equally important point is how much the fuel pump pumps. In other words, the pump may hum and buzz (power is being supplied), but not create the required pressure in the fuel line. The pressure in the fuel system with a working fuel pump must be more than 3 bar (which depends on the specific car model). The indicated pressure is accumulated in the fuel rail and has an indicator of 300 kPa and above.

To check, you need to measure the pressure in the fuel rail with a pressure gauge, taking into account the indicators that are the norm for a specific car model. Using the example of injection VAZs, the pressure when the ignition is turned on is 3 atmospheres, at idle the figure is 2.5 atmospheres, when you press the gas 2.5-3 atmospheres. This method will help you accurately determine:

• malfunction of the fuel pressure regulator in the rail;
• breakdown of the fuel pump or a noticeable decrease in its performance due to wear;
• severe contamination of filters (fuel filter and/or fuel pump mesh);

In the second case, when you press the gas, the pressure does not increase; in the latter case, the pressure gauge needle rises, but very slowly or jerkily.

A decrease in pressure below the norm will lead to the fact that the engine may not start or start with difficulty, stall, jerk, operate unstably and with failures. If this happens due to the fault of the pump and not the fuel filter, then there is a high probability that the coarse filter screen of the fuel pump is clogged. In this case, there is no need to change the fuel pump itself, since it will be enough to replace or even clean the mesh.

If you suspect that there is no voltage to the fuel pump, there is a quick way to check. It is enough to turn the ignition key and listen, as when you turn the key you should hear a slight hum from the fuel pump. If such a buzzing noise is not heard, it means there is no power to the fuel pump, there are problems with the wiring, etc.

Also in the general list of possible reasons why the fuel pump does not pump, the following are noted:

• failure of the fuel pump fuse;
• fuel pump relay failure;
• problems with the ground of the fuel pump;
• malfunction of the electric motor of the fuel pump;
• oxidation or damage to fuel pump contacts and terminals;
• the fuel pump itself is faulty;

Wiring to the fuel pump

On most cars, the wiring to the fuel pump consists of three wires: “plus”, “minus”, and also a wire for indicating the amount of fuel in the gas tank. If the fuel pump does not pump, then the cause may be a lack of power.

To check the power to the fuel pump, just take a 12-volt light bulb and supply it with power from the external connector of the fuel pump. After turning the ignition, the control lamp should light up. If this does not happen, then the problem is in the external circuits. If the lamp comes on, it will indicate the need to check the internal contacts of the fuel pump.

To check the external wiring, you should alternately connect the positive and negative contacts, which are removed from the fuel pump power connector, to the ground of the pump. The contacts must also be connected to the fuel pump relay. If you place the negative contact on ground, after which the ignition is turned on and the light comes on, then this means that this contact is faulty. If the light bulb does not light up, then problems with the “plus” are obvious. If you place a contact on the relay and the light comes on, there is probably damage to the wire on the section that connects the relay and the fuel pump itself.

Fuel pump electric motor

If checking the pressure in the fuel rail and the external wiring to the fuel pump gives positive results, then you should check the fuel pump motor. This electric motor is responsible for circulating gasoline inside the fuel pump.

When checking, you need to take into account that the terminals on the fuel pump themselves tend to oxidize, as a result of which power is not supplied and the pump does not pump. In this case, the motor is working, but the terminals need to be cleaned or re-soldered.

Automatic headlight switching diagram.

Modern cars use an automatic headlight switching system. It can be performed using various algorithms. In some foreign-made cars, the headlights turn on when the engine is started, in others when natural light decreases (at dusk, entering a tunnel, etc.). On domestic cars, this scheme is used on the Priora luxury version. In these cases, the headlights are controlled by an electronic unit. This makes troubleshooting somewhat more difficult, and in some cases it is impossible to do without computer diagnostics.

Replacing wiring

Wiring for a Gazelle 406 engine with pinout of ECU connector terminals.
Changing all the electrical wiring of a Gazelle when replacing an engine from 402 to 406 is of course not impractical.

The fact is that on newer versions of Gazelles, the connection diagram of certain devices also changed:

1. Gazelle 406 wiring is integrated into the standard electrical system in the engine compartment;
2. electronic components and control devices are connected using terminals;
3. The voltage and correct connection are checked using testers.

After assembling the wiring into a single whole, its functionality is checked. Subsequently, the operation of the power unit is adjusted.

Conclusions: Replacing the power unit inevitably affects the change in the standard electrical wiring of the car

That is why it is important to have a visual aid at hand when carrying out such an operation, and the Gazelle’s factory wiring diagram will allow you to avoid mistakes

Structural structure of the Gazelle fuse box

The electrical circuit protection system in Gazelle cars is implemented using a two-level model, which provides additional stability in the operation of electrical equipment and has the following features.

Fuses for Gazelle electrical equipment

The first protective level is provided by power fuses located in a separate mounting block under the hood of the car. Their operation is designed for a significant change in current in the circuit, and their main purpose is short circuit protection. In this case, two main circuits of the electrical circuit are separated, including:

• main positive circuit, excluding lights, generator and starter;
• positive generator circuit and light circuit.

In modifications equipped with an anti-lock braking system, two additional electrical fuses are installed that are directly responsible for this function.

Further modernization

Plans to increase sales volumes were not destined to come true. There are several reasons for this:

1. Quite high costs of operating a GAZ car with low functionality;
2. Obsolescence of the design in terms of passive safety;
3. Poor body corrosion resistance;
4. Lack of comfort features.

The wiring diagram of the GAZ 31105 with the Daimler Chrysler power unit complied with European standards. All this forced the automaker to engage in deep restyling, as a result of which the GAZ 31105 model appeared in 2004.

Among its features it should be noted:

1. DOНC power unit with a volume of 2.4 liters from Daimler Chrysler;
2. Electronic throttle pedal;
3. A new instrument panel, redesigned to meet safety requirements;
4. A control panel for power windows and exterior mirror adjustment located on the driver's door;
5. New headlights and taillights;
6. Air conditioner.

All this led to the fact that the electrical wiring diagram of the GAZ 31105 changed radically. Although the car became more similar in functionality to its foreign counterparts, it nevertheless could not compete with them.

3.9 / 5 ( 74 voices)

Model 3110 of the Gorky Automobile Plant was launched into production in 1997 and was conceived as a more modern and improved solution, comparable to the equipment of the middle class of foreign cars, while the price was noticeably lower.

But as time has shown, this modification also turned out to be uncompetitive, and therefore, after several years, its production was completely discontinued, but there are still many cars of the model in question on the roads, so the GAZ 3110 wiring diagram will be useful to those who carry out repair work.
