Alternator guage pegged out question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I may possibly have some of the particulars wrong, I'm going from memory, but think I'm real close. Buddy called me last nite, mentioned his alternator guage was "pegged out", showing I guess a severe overcharge situation. It's (IIRC) a 03 SS Silverado with (IIRC) the 6l Vortec engine. He said he already replaced the alternator (yesterday), and that did nothing to change the situation. My first thought, not being familiar with anything newer that 93, was the internal regulator. That's when he informed me he had replaced the alternator.

Anybody have experience with this, or any ideas? Thanks!
