Check out of charging system

From orange wire terminal on back of alternator to ground for voltage regulator - 12.5 volts (battery geting a little low). No change when I reved it up. The regulator was plugged in.

Unplugging the regulator and jumping the two terminals the voltage from alternator to regulator ground was 14.5 volts and as I reved it, it was climbing to 17 to 18 volts.

Looks like alternator is putting out OK. Back to the regulator?

Yes, the alternator is working. Try whacking the regulator with the handle end of your screwdriver and then plug the plug back in and wiggle each wire going in to each side of the male and female ends of the plug.

The whacking-it-with-a-bigger-hammer trick didn't work and I've had that thing plugged in and unplugged so many times I'm about to wear it out. I went down and ordered a mechanical unit. At least if it doesn't work I can take it apart and figure it out.

This is the same frustrating experience I went through with my 67 GTX last summer and it was the electronic regulator on it also.

Thanks for the help Patrick.
