Strange experience on Saturday. Drove my '06 Wrangler Unlimited over to a buddy's house. Started to leave but Jeep wouldn't start.
I've never seen this before. Guages were going haywire. With key not in ignition, and either door open, guages would swing back and forth.
Tried to jump it off and all it did was click and guages would go crazy.
I've had battery failures before, but never saw anything like this.
My buddy didn't have any tools so I got a ride home and returned with a tool box.
I pulled the battery and took it to Autozone to be tested.
Battery registered 13V but the guy said EVERY cell was bad.
Long story short, replaced battery and all is well.
Anyway, just thought I would share.
