Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Standard version of the brake light operating diagram

Power is supplied to fuse F17 from the battery, then the current goes to limit switch contact 11, and then, if the limit switch is closed, a circuit is formed with the filament of lamps 7. But note: part of the circuit is relay K1, more precisely, its contacts 5 and 4.

Basic network diagram

A complete electrical diagram with explanations of the VAZ-2112 car is here.

If the brake lights do not light up, on the VAZ-2112, as on all Tens, check one fuse. It is called F17 and is located in the mounting block to the left of the driver.

Main mounting block

It is important to know: voltage is always present at one of the fuse terminals. Check it out!

A few words about the “serviceability relay”

The lamp health relay is called K1, and it is the largest in the mounting block. If you remove this relay, then when you press the pedal you can dial the voltage at terminal 5 (but not 4). Look at the diagram again, and it will become clear what we are talking about.

The largest relay in the block

All relay contacts are numbered. Check the voltage at the block terminals:

• 6 – “mass” potential;
• 2 – voltage “+12”, but only after turning on the ignition;
• 5 – “+12” by pressing the pedal;
• 4 – the terminal rings like a ground tap.

If the potential “0” is not generated at terminal “4,” it means that the lamp filaments are burnt out or there is a break in the wiring. Now consider something else: the ground potential has been detected, but the lamps do not light. This is where suspicions of a short circuit arise.

New model power supply

What does the relay do?

We turn on the brake lights forcibly

Relay K1 is successfully replaced with a pad with jumpers. In Fig. 1 just shows its diagram. If there is no such platform, you can temporarily close contacts 4-5. First, check everything mentioned above.

Have an observer watch what happens to the lamps. Press the pedal with one touch and release it. If the lamps do not turn on, check that the fuse is working properly. It's burned out, which means you're looking for a short circuit.

How to and how not to check the “0 Volt” potential

Let’s agree right away that we only work with a voltmeter. Voltage “+12” is caused by connecting one probe to ground. The presence of potential “zero” is checked differently: any of the probes is connected to a terminal with positive voltage, and then the second probe is connected to the wire being tested.

How to connect a voltmeter

Consider the error: one probe is connected to ground, the second to the terminal being tested, and vol. Here they conclude that there is a “mass” potential, but this is wrong! If the contact with ground is broken, the device will also show “0”. That is, the number “0” does not contain information.

Relay and fuse blocks VAZ 2112: description and explanation

Modifications of mounting blocks and fuses of the VAZ 2112 have changed more than once during the production of the model.
Radical innovations were introduced only in 2002 after the appearance of a 16-valve injector. In 2006, there was only one unit in the cabin, and in 2007 a console unit was added to it. This happened thanks to changes in the shield and gearbox, and the addition of a Europanel. The cover of the main unit became hinged, which simplified access to the fusible elements. Separate inserts outside the mounting blocks, for example, under the brake pad, have been preserved.

Electromagnetic relays

To relieve the car switch contacts from high current consumption, electromagnetic relays are used in the electrical circuit. There are 8 of them in total:

• K1 is responsible for the serviceability of the lamps;
• for turning on the front window wiper - K2;
• for turn signals and hazard warning lights – K3;
• for low beam headlights - K4;
• for turning on the high beam - K5;
• for heating the rear window - K7;
• for fog lights located at the rear - K8.

The block contains relay K6, which is additional. Before installing a new element into the system, check the wiring for short circuits, otherwise the parting that is protected by the fuse element or the fuse itself may fail. The described block is the main one, but the only one in the VAZ-2112 electrical circuit.
