Thank you for catching my mistakes. I thought the 4g63 was around 160, Saturn 200, and ours was around 190. Guess I was off my 100 :P The built in voltage regulator is exactly why I'm currentoy running the 4g63 alternator. I kept having issues.with the external regulator so I did away with it, but the 4g63 alternator just isn't keeping the voltage where I would like it. Once.i start the car the volts are only around 10.5/11.2, once I keep the RPMs around 2,500/3,000 RPMs for about 10 seconds the volts will stay around 12.5/13.3. Sometimes a little higher but not often. But it is ok for the field wire to.be tapped.directly to the positive terminal? I know it sounds weird but I just wasn't 100% sure that was the correct location.
