Charging system (again)... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I posted here about a week ago that my charging system was acting up. Dropping voltage it seemed like only in the morning and so on. Well a couple of nights ago I had to go out at midnight and jump a buddy off. I noticed while we were talking there was a grinding noise coming from the alternator. Tonight I replaced the alternator. Now I notice a visible brightening/dimming of my dash lights with the engine RPM's. Any thoughts on what I should check. BTW with the new alt the voltage is yet to dip below 13 on my gauge.
