So picked up this beater bike and it came with an aftermarket electrical tach that isn’t hooked up. Bike originally had a mechanical tach? Anyways I am trying to find a tach signal to hook this up. I have purchased a tach signal converter for dual coil setup. It suggests tapping into the negative signal from each coil (with each coil having a negative and positive wire)
The problem is I only have a single wire from CDI going to the coils which I am assuming is positive. Does anyone know where else I can tap into the system to get the required tach signal? I can post a copy of the wiring diagram if this will help.
