==References====External links== much more I need to restore my speed indicator in AI.
That the mistake probably a cold soldering point (so my research
) is quite certain 
But again the symptoms:
Tacho needle/speed indicator is fixed (always more and more often) at zero, sometimes it jumps wildly up and down, sometimes it stays constant... Through a strong knock on the amature board (if tacho needle is dead) she jumps back up to the current speed in 2 of 3 cases - sometimes a few seconds until then again to zero, sometimes minutes - sometimes until the end of the ride.
Think of this as quite clear where to look for the mistake
What I just don't know now, I have the AI in my hand and opened - where/how do I look for the mistake now and what do I do?
To remind me that there was something to admit in the FAQ part - if so, then the entry has been deleted.
Greetings and thanks to all the answers
Philip
