Went to get in my jeep no interior lights came on or dash but the headlights did. Turn the key on and none of the dash lights or interior lights came on still but the radio, and headlights were on and the wipers were on and wouldn't shut off. Anybody see this? It has 1000 miles all I have done was install TL with pwm adapters and rigid duallys on a switch.

 

Disconnected the battery and everything went back to working still scratching my head

 

Anybody I think it might have been the computer.

 

Probably I glitch. Disconnecting the battery or having rig parked for the night tend to fix a lot of those type of issues.

 

I Know if the battery gets too low the computer will sometimes do crazy things. But yes just disconnect it for a few minutes and see if it is ok.

 

CMOS maybe ??

 

It cranked right up with no estimations. And it has worked fine since disconnecting.

 

Friend of mine picked up a 12'Arctic JKU, had same problem Friday. Was loose battery terminal on negative.

 

Same here on my 2012 arctic negative terminal. I just went to napa got a terminal with a extra spot for the two connectors. Jeep says the terminal is a non serviceable part. Not letting them touch my harness.
