How to connect a digital voltmeter to a vaz 2106. Clock voltmeter on the "six"

A voltmeter is a very useful instrument, especially when there is a place to install it. In the well-known "six" with a voltmeter, you can replace the regular clock, and this can be done in a few minutes.

The watch is sealed in the torpedo hole with a plastic ring, which is visible in the middle of its case.

After pulling the clock out of the torpedo, disconnect the wires from them and pull out the light bulb. We do not touch the lamp - we will use it for a voltmeter, and securely lay the wire terminals under the torpedo so that they are away from metal parts.

We connect the voltmeter

The UAZ voltmeter has only two contacts: a "plus" and a common "minus" to power the voltmeter and the backlight. "Plus" on the light bulb is supplied separately directly to its cartridge

The voltmeter should start working when the ignition is turned on. To achieve this, you can connect it through a relay, as described in the article "", but we are considering an easy way, so we will connect to the glove box backlight wire. Voltage appears on it when the ignition is turned on.

You can connect a voltmeter to the VAZ-2106 with a wire with a cross section of 0.5 mm. When connected to the backlight of the glove compartment, one meter of wire is enough for the eyes.

This is a cartridge with a glove compartment light bulb. Located in the upper left corner next to the cover

To connect, open the glove compartment. At the top left is a cartridge with a light bulb. The “positive” wire that goes to it needs to be eaten, then strip the two resulting halves, an additional wire for the voltmeter, and then these three wires together. Insulate the connection!

There is practically no room for manipulation in the glove compartment, so the above work can be done by pulling the necessary wire from under the torpedo through the same clock hole.

We measure the wire that we connected to the backlight of the glove compartment in such a way that it is enough to install the voltmeter and that it is not tight. Next, we bite it, clean the part that comes from under the torpedo, and put it on the “positive” terminal on the voltmeter case.

With the rest of the wire, we make the connection of the voltmeter to the “ground”, which can be done under the left torpedo fastening nut in the glove compartment. We lay to the nut, laying a small free play, and bite off the excess part, if any.

Now we clean the wire from both ends. On the one hand, we crimp another “mother” terminal, and on the other, a round “under the bolt” terminal. We put the “mom” on the second terminal of the voltmeter, unscrew the torpedo fastening nut with the key to “10” and twist it back, after putting the round terminal on the stud.

It remains only to insert the cartridge with the bulb from the clock into the appropriate socket on the voltmeter case and we can assume that the work is completed.

This is how the voltmeter is illuminated when the side lighting is turned on

We dress the negative terminal on the battery, turn on the ignition. The voltmeter needle should sharply set to a certain value. The readings of the device will be underestimated due to the fact that it is connected to the interior wiring, and the voltage in it is lower than at the output from the generator. This happens because of the numerous contacts "along the way" to the salon.

To get rid of the influence of the contacts and get the most accurate voltmeter readings, you can go the more complicated way and arrange a complete connection scheme. How to do this is described.

If you are the owner of a VAZ 2106 car, then you would probably like to have a voltmeter in your car. In this article, I will tell you how to install a voltmeter in a VAZ 2106 car.

The voltmeter will be installed instead of the clock, this element will be installed in the middle of the car dashboard. Why exactly will we install a voltmeter in place of the clock? Watches in a VAZ 2106 car are not distinguished by reliability or originality. Most drivers have at least one watch in their car (for example, in the radio). A watch is not such a big loss, but a voltmeter will help you in operation. You will see the slightest deviations in the work of the car's generator. For work, we need: a voltmeter from a UAZ car, a wire 25 cm long, a “mother” type terminal. Be careful when working with electrical wiring. Disconnect the battery before starting work. First of all, it is worth dismantling the clock from the torpedo of the VAZ 2106 car. Pull the clock out of the torpedo, you should also remove the cartridge with the backlight from the clock, remove the o-ring from them. We will connect the voltmeter through the positive wire, which is on the bordochka connection lamp. The voltage on that wire appears when the ignition is on, so the voltmeter will function with all other devices. It is impossible to use wires from the clock, since the current flows there constantly, and the voltmeter will always function. Accumulator battery the car will be heavily discharged.

We take out the cartridge with the lamp from the switch, remove the lamp power wire from the terminal, splice or solder the wire to this wire and assemble it in the reverse order. Attach a female terminal to the other end of the wire. Remove the mount from the voltmeter. The voltmeter itself should be tightly fixed in the hole, to do this, wrap the voltmeter in several layers of black tape, then put the voltmeter into the watch's o-ring. Throw the black wire of the clock onto the negative terminal of the voltmeter, and the wire we have extended must be connected to the positive terminal. Insert a cartridge with a backlight into the voltmeter. Insulate the end of the second wire from the clock, otherwise a short circuit may occur. Install the voltmeter in the standard hole from the clock. Now, when the ignition is turned on, the voltmeter will show us the voltage in the network. Of course, the device will not be able to show you the most accurate voltage, since everything in this world has errors. After installing the voltmeter, you can always monitor the voltage in the on-board network, and with the slightest deviation, you can quickly fix the problem.

Perhaps, if not all, then many owners of the "six" (BA2106), in addition to the set of instruments provided by the designers, would not refuse to equip their car with a voltmeter. Installing it is not difficult, and for this you will need the device itself, a few screwdrivers, wires and a little of your time.

To do this, however, you will have to sacrifice hours, because. a voltmeter is most often installed in their place in the middle of the torpedo. This loss is not significant, because the watch is not characterized by great originality, and many drivers have wristwatches, but in operation a voltmeter will come in handy more than once. Indeed, thanks to this device, you can see even minor malfunctions and fluctuations in the functioning of the generator and quickly respond to troubleshooting.

By the way, the voltmeter from the UAZ car exactly matches the clock in size and is installed in the torpedo without any problems. Also prepare a female terminal and a wire about 25 cm long. Exercise extreme caution when working with electrical wiring.

First you need to remove the terminal from the battery. Then dismantle the clock from the car torpedo. Pull the watch out of the torpedo together with the watch cartridge and the backlight, while removing the sealing ring from them. The voltmeter is connected by means of a positive wire, which is connected in the glove compartment to its backlight bulb.

Voltage is applied to this wire after the ignition is turned on. Therefore, the voltmeter will function in the same way as other devices. It is impossible to use wires from the clock, because there is current here all the time and the device, accordingly, will always be on. The battery from - this can be severely discharged.

After pulling out the socket with the lamp, dismantle the light bulb power wire from the terminal, and then solder or grow the wire to this wire and assemble in reverse order. At the other end of the wire, do not forget to attach the “mother” type terminal while removing the mount from the voltmeter.

Directly, the voltmeter itself is tightly fixed in the mounting opening of the torpedo instead of the clock, for which it is necessary to wrap the device with electrical tape in several layers and insert it into the sealing ring of the clock. The black wire of the clock is connected to the negative terminal of the voltmeter, and connect the pre-drawn wire to the positive contact. Then you need to insert a cartridge with a backlight into a voltmeter and fix it in the regular hole of the clock and turn on the ignition, the device will display the value of the auto network voltage.

A watch is not such a big loss, but a voltmeter will help you in operation. You will see the slightest deviations in the work of the car's generator. For work, we need: a voltmeter from a UAZ car, a wire 25 cm long, a "mother" type terminal. Be careful when working with electrical wiring. Disconnect the battery before starting work. First of all, it is worth dismantling the clock from the torpedo of the VAZ 2106 car. Pull the clock out of the torpedo, you should also remove the cartridge with the backlight from the clock, remove the o-ring from them.

Motorists, who were looking forward to the appearance of the prototype of the six - VAZ 2103, were happy to learn that there was a clock in the instrument panel that had not changed and the "troika" were also equipped with them. At that time there was no mobile phones, and the chronometers on their hands were the source of accurate time for drivers. Such devices in the cabin were considered the lot of Western-style cars and were, without exaggeration, a luxury for the then Soviet motorists.

With the release of the "six", the VAZ 2106 watch did not undergo fundamental changes. The clock connection scheme has not changed, which can be viewed here. circuit diagram clock is tied to the ignition switch and safety element box. At the same time, the kinematic circuit for connecting the VAZ 2106 clock is designed in such a way that the chronometer works regardless of the position of the ignition key, i.e. the clock on the "six" works even when the ignition is off.

If the problem is connecting the VAZ106 clock, then there is nothing complicated in this technical operation, and no difficulties are foreseen. At the same time, when solving the problem of how to connect the clock, it is necessary to bring one wire to ground, and connect the remaining two plugs to +12 volts to the clock network and to their backlight. According to the color of the wires, which can be different, the positive wires should be of the same color, usually red, and a black braided wire should be attached to the ground.

When buying a VAZ 2106 watch, the price of these products is small, but due to the fact that they are morally obsolete due to their low information content, motorists install the same chronometers from the “seven” instead of watches for the first time, and many tune this device with LED backlight or insert such a timing device from foreign models of vehicles.

Given the simplicity of the design, this element of the instrumentation of a car rarely fails, therefore, it is quite rare to resort to such an operation as repairing a VAZ 2106 watch. However, in practice there are cases when watch repair is simply necessary due to their failure.

Watch repair "six"

A malfunction of the chronometer may be of the following nature:

a mechanical defect in the “six” watch mechanism, in this case, do not repair, but immediately proceed to replace the product;
malfunction of the instrument backlight system;
breakdown of electrical parts or their connections.

In case of malfunctions of the electrical part of the product, which can be eliminated during repair work, it is necessary to dismantle the device and replace defective elements.

Dismantling and installation of the chronometer

We are preparing vehicle and tools for repair work;
Disconnect the negative wire from the battery (disconnect the "mass" of the car);
Using a screwdriver, we pry the plastic ring through the grooves on the side of the clock and pull the product out of the installation site;
The retaining ring is dismantled with the product;
When replacing the backlight of a VAZ 2106 car clock, a W3W electric lamp is used, which must be unscrewed from the installation cartridge and replaced;
When removing the device, we mark the wires and disconnect from the contacts of the product;
During installation (reverse installation), we fasten the mounting ring, aligning the protrusions with the holes on the instrument panel;
We connect the marked wires and fix them on the instrument panel.

Clock voltmeter on the "six"

The instrument panel of the "six" is quite informative, there are instruments for measuring speed, speed crankshaft engine, oil pressure sensor, coolant temperature sensor and a sensor showing the remaining amount of fuel in the fuel tank.

As for the operation of the generator device, in the absence of energy regeneration, the “control” lights up. But this already becomes known after the failure of the generator. To prevent the creation of such a situation, it is advisable to install such a device as a VAZ 2106 voltmeter clock, which is already equipped with VAZ-2105 cars, 07 of the last years of production.

For this installation you will need:

UAZ voltmeter,
Electric wire 20-25 cm,
Dedicated input connector ("female")

Important note: when repairing electrical appliances and connecting circuits, it is necessary to de-energize the equipment by removing the negative battery cable from the connector. This is necessary to prevent short circuit and failure of the vehicle's electronic equipment.

Algorithms for setting the clock of the VAZ 2106 voltmeter

We dismantle the factory clock on the VAZ 2106 from the attachment point, disconnect the supply wiring;
We connect the clock of the VAZ 2106 voltmeter to the positive contact of the backlight of the compartment box. The contact is activated when the ignition is switched on.
It is impossible to apply the factory electrical circuit to the chronometer due to the constant activation of the contact, which can lead to battery discharge in case of long-term storage of the vehicle;
We lay the leash from the place where the chronometer is fastened to the sidewall of the storage box to the place where the device is illuminated and connect the wires in the necessary way, and fasten the output end of the wire with a “mother” type connector;
Remove the fastener of the voltmeter;
For a tight fastening of the voltmeter, we wrap it with several layers of fabric insulating tape. We install the ring - the seal from the chronometer, the illuminated cartridge and connect the wiring;
We carry out the insulation of the old wire from the "six" of red color, because. it is under constant voltage.

After that, we install a new device in the place of attachment.
