happy you found the problem, I had to return an alternator last year because it was bad, but it did test as bad at the store. So I am not suprised. Really somtimes it is the simple things though.

Lesson learned: Don't always trust Autozones testing!!!!!!

New alternator did the trick... She's running like a champ.

Thanks to everyone who helped us out with this. My son and I are very grateful. Even though it ends up that we wasted A LOT of time on this, the knowledge we've gotten gained is invaluable.

Good news. Hope you didn't have to fight with them too hard to get the exchange.

Replace "wasted" with "spent" and "Don't always" with "Don't ever"...
