I jump started a friend’s truck last week, but he had the cables on his battery backwards (even after me reminding him to check). The connection was made for about 3 seconds before we stopped and realized what was done. 3 days later I woke up to a dead battery after driving it the days prior. I figured since it was 2.5 years old and had been incorrectly jumped, it was dead. I got another battery and all was well until this morning when the new battery was dead (another 3 days later). 2 hours on a battery charger and it was good to go.
My battery is charging while the truck is on (approx. 14v while running), but slowly loses a charge when off. No trouble codes. My best guess is a diode in the alternator went bad. Anyone else have any suggestions on what it could be?
