Relay and fuse block VAZ 2106: decoding of circuits. VAZ 2106 fuse diagram

VAZ 2106 fuse box pinout, diagram

If you have any problems with electrical equipment: the low or high beams have disappeared or are not working, the turn signals, stove, cigarette lighter, fan, wipers are not working, the signal has disappeared, etc., then this could all be the reason that the fuse has blown. This means it needs to be replaced.

To do this, you need to know the location of the mounting block. And it is located under the steering wheel, on the left side. In order to understand what the VAZ 2106 fuses are responsible for, you need to look at the simple pinout of the old fuse block (FB) and see the description below.

Relay VAZ 2106

The following shows the location and designation of each factory relay:

1. Voltage regulator, which is responsible for proper charging of the battery. Located on the left mudguard.

5. Turn and hazard warning relay. It is located behind the instrument panel, approximately behind the tachometer.
6. The wiper relay is located on the left side, under the instrument panel.

The video below clearly shows where which relay is located.

Below is the pinout of the new type of power supply or, as people say, “Euroblock”. The diagram also shows which fuse is responsible for what.

How to identify a blown fuse

1. visual inspection;
2. diagnostics with a multimeter.

Visual inspection

It is necessary to check the integrity of the metal partition of the element. If it is broken, then the insert is burned out.

Diagnostics with a control and a multimeter

When an element burns out, the integrity of the jumper is not always compromised. It wouldn't hurt to check with a multimeter. The probe is applied to the fuse, the device is turned on, and if it shows resistance other than 0 Ohm, then the element is broken.

Replacing the VAZ 2106 fuse box with a “Euroblock”

And finally, for those who don’t know how to replace the old model with a “Euroblock”, the following information. There is nothing complicated here.

You just need to follow the instructions below:

1. First you need to disconnect the minus from the battery.
2. Use a 10mm wrench to unscrew the old power supply. In this case, the wires are not disconnected.
3. According to the diagram above, wires and jumpers are installed.
4. It is important to install jumpers only on those wires that carry voltage from the engine compartment.
5. Jumpers are installed between pins 3-4, 5-6, 7-8, 9-10, 11-12.
6. Next, the wires are removed one by one from the old device and attached to the Euroblock.
7. At the end, check that the connection is correct (for example, with the low beam on, if you pull out the 5th fuse, the left headlight should go out).
8. All other circuits are also checked.

The video below clearly shows how to replace an old power supply with a Euroblock.

Removal and replacement process

There is nothing difficult in the process of changing power supply parts, so we will not describe this process. But we will tell you how to replace an old-style power supply with a new-style device.

1. First of all, disconnect the battery. Now open the driver's door and use a screwdriver to pry out the two fasteners securing the decorative interior trim. Move it to the side and you will see a block. Using a Phillips screwdriver, unscrew the screws securing the power supply. Do this carefully so that the wires do not fly off the terminals in the process.
2. Once the power supply is unscrewed, move it down. But do not pull it too hard to avoid breaking the wires. Note! Jumpers must be installed on those wires through which voltage comes from the engine compartment. Do not connect the jumper after the fuse itself, otherwise this will result in voltage passing through one part to power several electrical components.
3. The order of installation of jumpers should be as follows: 3-4, 5-6, 7-8, 9-10, 11-12, 12-13.
4. Now you need to remove each wire one by one, starting with the first fuse from the old power supply, and mount it on the new one. Perform this operation with each contact, until the very last wire. When all the contacts are in place, you should check whether you did everything correctly. In particular, you need to turn on the voltage source and remove the corresponding fuse. If the device stops functioning, then all actions were performed correctly. For example, turn on the low beam headlights and remove one of the power supply elements responsible for the left or right headlight. If it goes out, then you did everything right.
5. Check each fuse in the same way. If, when dismantling the element, the device continues to work, then the jumper is most likely installed incorrectly, so double-check the connection diagram.

This completes the replacement of the power supply with a new type device. As you can see, there is nothing difficult about this, but if you are not sure that you will do everything correctly or cannot distinguish the blue wire from the red or green, then entrust this matter to an electrician.

Problems with the mounting block and their solution

Many owners of "sixes" are faced with the problem of frequent power surges. It can be caused either by a malfunction of the generator or voltage regulator, or by problems with the mounting block. If you have established that it is the cause of the problems, do not rush to replace it with a similar one, just a new one. Better take a closer look at the mounting block from GAZ-3110. How is it better? The fact that it will allow installing fuses on the VAZ-2106, which are equipped with “installers” of modern cars. They are easier to buy and more reliable. In addition, the Volga mounting block is much more compact than the “six” one. It is made in the form of a single strip, accommodating only 12 fuse links.
