Hi I'm kinda new to the jeep life and I'm already running in circles trying to figure this one out. I was driving my xj the other day and I shut it off to go grab a pizza and when I came back out the jeep appeared to have a dead battery. So I jumped it and the while way home the battery meter kept jumping around like crazy. So I shut it off and it wouldn't start back up at all not even an effort to. So I threw the battery on a charger and today I went to start it and it sounded like my starter went. So I jumped and brought it to advanced for a starter and alternator test and it said my battery starter and alternator are fine and it's been starting up no problems and the battery has been pretty steady. Any ideas ??

Sometimes batteries develop an internal short. Sometines it's On heavy load like starting. Sometimes alternators fail and take the battery with them. Sometimes it's just a fuse.

When the Jeep wouldn't start did you have Lights? Or did it seem like a completely dead battery?

I'd guess battery based on what you've described.

Is your starter coated in oil from leaking oil filter adapter seals?
