We are in the final stage of restoration, the tach do not work, the battery light go off, but no the revolutions, I am wonder if I did connect the wires wrong, if anyone know the correct way to connect by colors.
The 79 I'm working on has an electric tach. Two wires, one 12V and one a signal from the minus side of the coil. Alas, both wires are white.
I have the wiring diagram in a PDF from papajam. Tell me your email and I can send it.
