Still not charging!!! Okay, here's the deal: I had the alternator checked by Autozone and it passed fine. I put a new regulator on. The ground is good, the wires are good, the battery checks good (one year old), no fuses blown, and no shorts. Yet, it does not charge.
I get 12.44 volts across the battery terminals with the truck running. When I turn on the lights and heater fan, it drops to 12.23 volts even when revving the engine to about 2000 or more RPM.
What am I missing?
