thanks for the replies everybody! goal for the time being is just to have the car running safely and reliably. The voltage regulator on the firewall appears to be bypassed all together, nothing hooked up to it at all. The GEN light does come on when starting the car and then goes off like it should, not sure how it's wired into the system lol. Tested the battery with a multimeter, 14.10 volts when the car is idling, so the alternator appears to be charging....the car has an aftermarket tripack of guages, one of them being alt. volts, not working, can I rUn the white leaf from the alt. to this guage?
