Hey guys my battery light came on while driving today all gauges lit up and speedometer and tack went crazy and radio shut off. I kept driving until I got to work.
My buddy/mechanic hooked his computer up to it. He said code for battery output is reading high. Why? Any suggestions before I go to the dealer. It's a 2015 with 9k on it jku. Aux led windshield fogs and 21" light bar on bumper and truck lite led headlights. Those are my electrical upgrades.

 

The nuts closest to the battery terminals are what tighten your connections, both positive and negative. Make sure none of your accessory wires are under them.

 

Ok thanks I'll check it out tomorrow morning. I hope that's it.

 

It's so new I'd say the odds are high. Let me know.

 

This is what I have. Before I picked up the jeep I had the dealer at a tow hitch and 7 pin connector. I believe that's what that is from. My 14 didn't have that on there.

 

It looks like the dealer lost a negative nut and they should know better than to put the wires where they did. You need to move the red, white, and black wires out from under the aforementioned nuts. You can either move the ground wires to another spot on the chassis or get a nut to replace the missing one and put the black and white ground wires there.

 

Thanks bud I appreciate the help I'll get on that right away. I'll let u know how I make out.

 

You're welcome. Please do.

 

Ok so I moved the red wire over to the right. Then I took the black wire off the negative and mounted it elsewhere. Now my problem is the white wire which is from the factory also. If I replace the nut that is missing can I move the white wire over to the right?

 

Replace the nut and put the black and white wire to that post
