Let me talk about my friends problem briefly, I disassembled km meter, I changed the light bulbs, I changed the bulbs ... Then I came to my mind, I thought, it was not difficult to guess after it. when I insert it, for example, when I turn the key to turn the tachometer lever on it, it bounces a little bit. Normally the car is 90 dions when it is at 2 thousand rpm, now the tachometer shows 90 at 3 rpm, I am not sure even the speed is correct. I have put the hands in place, there is a method for adjusting the buttons ... I have done something, for example, I have brought the hour hand to 50, then put it counterclockwise around it and then leaned it on the piece of rubber that held the lower hand. ... but what exactly is the right water under it .... n has a rotating magnetic mechanism, attaching the needle and moving around & nbsp; the more turns you run in the opposite direction, the more strands in it come to the tensioner, for example, I had almost 90 speeds in my experiment but the needle showed 10 dislocated ... do you have a standard of it ... how can i fix it :)) it was long but per head It is not a topic that I hope you will understand, but, I think maybe friends whose mind is the same as me, to break the car, confuse your left, can help me .. & nbsp;
