I picked up my new alt yesterday and the back looked different. Both field terminals (not one field and one ground)were insulated. Rushed home today and installed it, what a big difference. The headlights and dash lights don't dim, the radio doesn't act up, the autometer amp gauge don't move around, and I no longer have a higher voltage at my battery that fluctuates. It holds nice and steady. A big thanks to all, especially RapidRobert for all you help.
