2000 k3500, 7.4 vortec with 0411 sap:
It got cold out, and the truck was weak to start— but it started. Battery was probably a little weak but it did start.
However the alternator didn’t start charging right away. It was as of the alternator wasn’t doing anything, verified by 11.2 volts at the battery.
After about 20 minutes it started charging like normal, and was fine on the drive after that.
It’s done this exact thing 3 times now. I put the battery on the charger just in case, but it didn’t seem to make a difference.
Any ideas what’s up with this behavior? Do I need a new alternator or is there something simple going on?
