The interesting thing about the voltage regulator is that my car came with a spare. I put the spare on the car while I was trying to figure out what was wrong. After I fixed the generator I held the field wire against battery and measured armature output. Sure enough it went to full output which showed the regulator was bad. (you nay remember that when I did that before fixing the generator the field wire got instantly too hot to hold). I put the original regulator back in and everything works now. I would have thought that the original regulator would have been fried after being hooked up to the grounded field wire for who know how many years.
