I'm going to attempt replacing my alternator one more time, but I do have a question since this pertains to the 5.3.
Why I'm looking to replace;
My current one seems to be overcharging the battery, as I found out last week where I discovered battery acid was coating my inner fender and the battery holder. The shop looked over the battery, and replaced whatever fluid was lost and it seems to be in working order. Both keep passing the tests from Advanced Auto, and the shop tested it and found it to be working out as well. I'm honestly at a loss, I bought the battery, an Interstate T7(?) series that comes with a 4 year warranty that seems to cover it. I've taken it to an Interstate battery center, and they won't replace it unless its showing failure. Since it was installed, I've been dealing with issues where it'll drain over the course of 3 days. I've checked and cleaned the grounds in and around the engine bay, by following the manuals in Mooseman's sig. It's honestly becoming a pain, especially Sunday morning while working on the Envoy. It was a little low when I went to the gym, and during the course of starting her up, to turn the wheels while replacing my hub assembly was enough to deplete it. Which resulting in the starter just clicking. So I hooked up the Battery Tender and let her charge over the course of the day. So I'm not sure if the alternator is just not charging the battery enough throughout the drive, or the battery has a weak cell that is just not registering.
The current alternator is a ACDelco 334-2529A refurb, I was looking at Remy or DB Electrical. This is alternator #3, the previous one kept causing my headlights/dash to dim whenever I opened/closed the windows or made my headlights flicker while driving. (I have another thread from 2-3 years ago about voltage fluctuations). Though one thing has me wondering, why is there such a price difference between the AC Delco Alternator for the 360/370 platform versus the ones you get in the Yukon/Tahoe? (if they're interchangeable).
