The screws in the back of the regulator might be very tight. They appear to be phillips, but if you look really close, you will see little dash marks on them indicating that they are posi-drive. This is a weird little phillips bit that is spaced a little different. (This is just for your info)
Do replace the regulator first before trying anything else. Be sure the belt and the alt. pulley is tight.
