So, the first entry and the recent breakdown. In general, the speedometer got stuck at 120 km/h and wouldn’t let go. My father-in-law at the speedometer was 0, it was 120, if you go 50, then the speedometer shows 170 km/h))) it’s a very inconvenient thing that turned out like this. The tachometer was also downward by 500 rpm. I read here on the website who treated it. Reset the terminal from the battery, run a tidy test, etc. nothing helped. It was decided to remove the tidy and set the arrows by hand. I put it out, I think everything will be fine. I connect the device, run tests, what is the result? The tachometer needle still doesn’t show correctly (goes down), and the speedometer is fine at first, but then there are some crackles and it again starts to show incorrectly, going far beyond 200 and resting on the bottom of the dashboard... Taking a friend to help, we decided to open it completely and see how everything works there and what interferes with the shooters. After much thought and fiddling with a thin screwdriver, we uncovered the “motor” that turns the speedometer needle. The whole problem was that the gear on which the arrow was mounted was not entirely intact, or rather, 4 teeth on it were broken. Again we thought about how to solve the problem. Don’t buy a new device for 3400 just because of one gear... The solution was simple. I opened the temperature gauge motor and swapped the speedometer and temperature gears. Having empirically determined that broken teeth will not harm the temperature gauge. We collected everything except the temperature needles and speedometer. We connected it to the car and did a test so that the motors would drop to zero. Then I set the arrows evenly, ran the test, and lo and behold, everything works! Saved RUB 3,400.
