Cruising the jeep yesterday mobbin thru our new fresh snow, no problems. Ive been having issues with my driver side headlight but Im sure one of the bulb connectors is bad.
Anyway jeep running, driving great. This morning that same headlight is out so I disconnect then reconnect the ballast and it works fine. While im driving to work my radio kept turning off and on randomly. So i read on here that it could be a fuse. I pulled my jeep into our warehouse at work and reconnected the HID ballast and then went over to the fuse box and just gave them all a push making sure none were loose. Left the lights on and started the jeep and boy it barely turned over and then didnt want to idle. Got out and both my headlights were out and the radio wouldnt turn on. When I went to pull out it wasnt responding to giving it gas, it was hesitant to go.
What in the world just happened??
One minute running great, the next it barley runs..

Here's a pic of the fuses in your PDC that you were pushing, that is to say that the 'fuse box' is this PDC.


Check each fuse by removing it and seeing if it's blown. If there's any doubt, replace it.

So i did that and it ran great for a minute, headlights & radio working, then started idling really rough and died. Now just clicks when I hold the key...

Check the charging system and battery.

Even though it won't run, do the headlights and radio work when the key is turned to ON/RUN or ACC?

Might be a loose battery connection or corrosion in the cables. Starts but then rattles loose and dies because it doesn't have any power maybe? I know if my jeep is dead then I have to hold the gas to keep it running till it charges up enough. And I hope you have an upgraded headlight harness with those hid headlights because they draw a lot on start up and the xj harness isn't good to begin with.

Bad battery. Bad ground.

I got it running and tested the voltage and I was getting 10.89 and It would fall from there. Pulled my alternator and had it tested & advanced auto. It passed but boy was it making a lot of noise. The bearing was just about shot.. So I replaced that and its running great now. Im going to swap my battery terminals & I just got a new battery 2 weeks ago as the other would not hold a charge. Im assuming that was contributing to my alternator heading south.
Hopefully with the combo of a new batter, new terminals, & new alternator things should be good to go.
