Anyone out there know how to adjust a NAPA Echlin #VR412SB regulator? I have converted it to 12v, neg. ground and had the generator rebuilt w/ 12v field coils. My battery is fully charged. When I start the car at idle my volt gauge reads 13, with higher rpm it reads 16+. This seems to high and I don't want to burn anything up. Can I adjust this lower?
