Well. I changed out the new alternator and new serpentine belt. It charges now. I went to buy new batteries, and they only had 1 in stock. WTF.
So hopefully next week all should be good. 👍
Very odd, my fluke initially gave me only 13v last week when I started having the issue. Judt before...
GM trucks with Regulated Voltage Control (RVC) alternator systems include models from 2007 onwards, particularly the half-ton trucks and heavy-duty models like the Silverado and Sierra. This system is designed to optimize battery life and improve fuel economy by managing the charging voltage.
