That’s what I would do too. Check current draw. Realize that there is some drain 24/7 on it, such as the computer, clock, radio station memory, etc. Also check the alternator for it’s charging voltage and disconnect the the alternator when you pull one fuse at a time. A bad diode can cause a draw on the battery.
Correct. I had an alternator kill a battery. And I mean KILL a battery!
New alternator, new battery, everythings OK now.
