(Edit: This isn’t exactly true. I fixed my “current flow” problem but not the cutting out issue. See later posts for problems around the voltage rpm cut off)
I fixed my alternator voltage problem. With summer coming up it’s going to be a problem running AC and fans with my alternator voltage dropping out when I’m idling
I Ordered this pulley from summit racing. It’s smaller than any stock GM pulley. It does the job too. I don’t drop voltage while idling at 650 anymore. There are times when I’m idle drops below 650 and the voltage needle with bounce low. but with AC, blower on max, and fans running it doesn’t struggle.
