tach 76 corvette
I'm having a problem with the factory tach. If the switch is turned to the on position, the tach needle moves about past the zero position, below it. when the engine is started it does not move.
The car has a MSD ignition, the tach has been working off the MSD tach wire for about 15 years. The MSD tach still works, but not the factory. Does any one have the wiring diagram for the factory tach.
Thanks
