Hi, My tachometer doesn't work. The initial check does it but then the marker stays at 0. I have tested the instrument panel on another motorcycle and it works correctly. The fuses are all good and I have checked the wiring and apparently there are no shorts.

I have checked the yellow/green cable of the control unit and it shows the voltage indicated in the workshop manual, so I suspect that it works correctly.

Something similar has happened to some of you. thank you
