Default Re: Not getting power to coil

Electrical is not my thing so just a thought.
The coil runs on 8-9V. If you run 12v to an external resistance coil it could over heat and it burn out. After looking at the 64 wiring diagram. Its looks like the resistance wire start at the plug in the engine compartment. Disconnect it, turn the ignition switch to the run position. And check voltage at 18-p-3 on the R.H dash bulkhead connection in the wiring diagram. If 12v. Pull the resistance wire pin out and replace it with a new wire and connect it to the coil. Then connect the Pertronix to the coil.
Or disconnect the resistance wire from the coil turn the ignition switch to the run position. And check voltage on the wire it could be almost 12v. If it is then connect wire and the Pertronix to the coil.
I think the amount of resistance in the wire depends on the length of the wire, the longer the wire the more resistance. And the resistance wire should go to the "R" terminal on the starter solenoid.

And go I would buy an internal resistance coil just to be safe.
