Trying to figure out a charging system issue I'm having. My alternator doesn't appear to be putting out any juice... 12.7 volts by multimeter coming from the battery with no key on. 12.5 volts with car running. Idiot light on the alternator appears to be working. If the idle drops under about 400 rpm, my gen light will come on (making me think the light's working as designed, I guess). Voltage meter in the console shows a flat 12v while running (drops to 10v with headlamps lit). All that said, is the voltage regulator internal or external on 'teeers ('75 1.8). If it's external, how can I test it. Best course of action??? Thanks all!!!
