    *UPDATE* I now have a new battery, a Duralast Gold. So far, after driving a good bit yesterday, it’s still hovering around the 14v mark, maybe just the age of the truck. And my alternator is not that old, maybe 5-6 years tops. I do however need to change my serpentine belt and install a new belt tensioner. I’m going to ask the GMC tech next week about it, when I take it in to have finally have the airbag recall fixed.

    Is it normal for the belt tensioner to wobble back and forth? Here’s a link to a video I just put up on YouTube.

    Ever since I upgraded to an AGM battery about 5 years ago, I’ve noticed that my voltage meter stays around 14 volts. No fluctuations at all. My alternator is an AC Delco DR44 160amp. Right after start up, using a voltage meter, the volts on the alternator are between 13.72 and 13.90. The tests about the same. I turn on my high beams, the heater full blast, engage tow haul mode, but it stays exactly the same. Would love to hear your thoughts. Thanks!
