Backstory:

Started putting a lift on the Jeep almost 2 months ago now. Forgot about starting it for awhile and had to jump it to start it about 2 weeks ago. Started and let idle to charge the battery. Started the next day and all seemed good.

Fast forward to this weekend. Went to work on it, hit the key fob and nothing. Dead from sitting again, which I assumed so I threw a battery charger on it. Went tonight checked voltage and was good. Opened the door and had no lights. Put the key in and turned on and had no gauges, radio, widows, ect. Tried to crank and it turns over no problem. Disconnected battery and let sit to try and reset everything with no luck. When reconnecting the battery I can hear the relays clicking in the under hood distro box. All fuses test good in there. Did minimal testing in car but did find I am only getting about 4 volts inside the cab, measured at the cig lighter and the ignition harness. Plan to poke around more tomorrow but looking for any insite.

 

Replace the battery and check the cables.
