Tach not working .

[Jurgen]

I have not spend too much time looking into this as i had other things to take care of first . Is there anything this care are known for to go bad ? My tach does not work at all . Its a 76 124 spider .

I've never had a tach fail. check grounds and the signal lead from the coil

Thanks guys . I was looking at the wire schematic last night and found that the brown wire was not connected on the coil .

Thanks

Would anyone have any photos so I know what I am doing in our cars?

Apparently if you just wait until the next morning it corrects itself Still could use the photos, I will try later
