Completely dead battery in minutes after a fresh charge.
My car died on my way to work yesterday very suddenly. All my lights came on, lost power steering, pulled over and stopped and the car died. Got it towed home and battery charged. I get it running and test the battery, shows 68% life left which is doable. I run a charging test for the alternator and it says no output. I come back out after 30 minutes because I was putting my daughter to bed and the battery is completely dead. It also smells like ozone a bit. I'm assuming a bad diode and the alternator is no good, but any second opinions before I go that route? I'm going to try the good ole, pull the negative cable trick when the battery is charged again. That's just going to take a while. It's also weird because I replaced the alternator like 2 years ago, idk what would cause it to go so suddenly.
EDIT: Well ... I'm super confused. Charged the battery - I have a trickle charger and just left it for a solid 24 hours. I hooked everything back up, ran some tests, and my tester said the alternator is fine, the battery is healthy, and now everything is apparently fine 🤣. Maybe there's a bad cell in the battery? Someone mentioned they had something similar and it was a bad BCM? Or maybe my alternator is on its way out and just cooperating for now. I honestly don't know.
