Hey everyone,
Today I installed new tach i ordered from Moyer and had it working fine though a bit jumpy especially at idle. I've wired it according to the instructions as well as chatting with Don last week, white wire is to negative side of coil, black to ground, red and green to ignition switched power.

Next i installed new electronic ignition. Black to negative red to positive and now tach is not working. Its intermittently jumping between 0 and 500. Wondering what a possible solution might be? I'd like to time the engine using Thatcth and ndutton method, but really want the tach to be working...

Thanks Trevor
