Installed new coil, now the tach acts funny
Well I consulted the Autometer website, and learned that with an orange ignition module, the green wire from the tach needs to go to the gray wire that goes from the module to the distributor, not the negative terminal of the distributor. The problem is that there are TWO gray wires going from the module to the distributor.
I called Autometer, and they weren’t much help. Basically they said I need to find out which of the wires “pulses.” I’m assuming the wire I need to find is the negative? The two wires coming from the distributor are red and black, and it’s my understanding that negative leads are usually black, especially when the other is red. Is this generally a good rule of thumb?
