What are the three leads on the back of the stock tachometer.

Asked by Freeryder73 Dec 12, 2013 at 09:33 PM about the 1973 Chevrolet El Camino

Question type: Maintenance & Repair

My tachometer does not work, every
time I try to connect what I believe to
be the wire that goes to the
distributer the car won't start.
