Alternator overcharging 01 Ford e350
I’ve got an 01 Ford e350 super duty colt club wagon with 163k miles that I’ve converted to a camper.
I’m about to install an alternator charger for my house(auxiliary) battery and I figured it would be best to test the alternator before I hook it up.
Here are my voltages:
Battery w/ van off: 13.3v
Van on (idle, no load): 14.6-14.8v
Van idle with brights, radio, and heat on: 14.6v
The battery is from 2012. And I’m not sure if that will play a factor. Also, the terminals are a bit funky with a little bit of corrosion (not much.
What steps should I take to troubleshoot this?

The charging voltage will be the same between truck and van, if you measure the battery voltage after the truck was running you will see a float voltage on the battery, if you wait about 1/2 hour and check again you should see the battery around the 12.8v area.
