67 GTO Tach problem
For the past month i have been trying to get my old tach repaired, but the part was on back order. Finally it came yesterday and I installed it right away.
However the happy ending i thought would come did not.
The new tach does not work at all. No movement.
I have the dash taken apart and just wanted to test the tach, so none of the other instruments in the cluster were hooked up.
When i started the car, and did not see the needle moving, i tried wiggling the wires a little and could feel a charge from the two black wires coming from the wiring harness.
In the attached pic, the old tach is on the left and the new one is the one screwed into the cluster.
If anyone can provide any advice I would appreciate it.
