Maybe since the VR went, could the alt be on the way out?? I could be wrong, but you should be getting between 14-15 volts out of the alternator?? Oh maybe when the young lad changed the VR, the new one didnt get mounted solidly??
Yeah it's mounted solidly. They Checked the voltage after the new one went on and showed 14.5 volts to the battery. I can take it tomorrow and get it rechecked now the battery has a full charge. If it only did it in park I would think it was the alt. but it also does it when I come to a stop at a light.
