Reply to "Lost the tach"

The 12v power source to terminal #30 on the relay is from the battery cable on the starter relay.

The car fires right up so there are no problems with the other wiring.

Just the tach.

The tach wire went to the ignition terminal of the coil. The Ignition switch wire (the wire from the ignition switch) was also on that terminal.

That wire from the ignition switch now goes to terminal #86 on the solinoid.

Where does the tach wire go to now?
