Off, you should see 12.3-12.6 VDC.
The battery tester said it was good and getting the 12ish volts it needed while off... will it still show the 14.XX while running if there is an alternator is having problems?
My question about charge times wasn't so much for the battery charger/tender but for the alternator... could the battery by at 60% because it was much lower from parasitic drain and the alternator just hasn't had time to charge it back up yet? I'm really hoping and praying its a simple issue and that I don't need a new alternator or belts
