I thought you said this was simple?
Everything seems to check out but it doesn't charge. Jumpering across the VR terminals and checking the voltage from the + starter relay to the neg battery cable I get 14.5 volts at idle. Ammeter is pegged. Plug the VR in and I get 12.5 volts throughout the the system and a slight discharge from the distributor I guess.
I put my VOM in the VR jumper circuit and got 12.4 volts is all. No change when reved up.
I ran continuity on all the wires and all passed. I checked all the grounds and they test good to the engine.
Seems strange that with the VR jumpered I'm getting 14.5 volts at the starter relay but only 12.4 volts between the yellow and blue wires in the VR plug.
My battery was down to about 50% so I put the charger on it. That's about my last hope - maybe it's just too low to charge somehow.
