I've been having an issue with my jeep losing all power. I think it may have started from a short in a faulty relay from my KC's. I live on the ocean and have replaced that relay twice due to corrosion. I was driving about a month ago and turned on my KC spots and my 02 TJ just completely shut off...engine and electric. I was doing about 60 on an unlit road with no other cars around. After 5 seconds of complete darkness the electrical came back and i was able to start the engine while rolling in nuetral.
I pulled the relay right after that and did not have any problems until a couple of weeks later when i put my key in and everything died. The battery had good charge. I would turn the key and it would sond like it was about to turn but then everything would shut off and come back about 5-10 seconds later. When it came back everything electrical worked fine until i went to turn the ingnition. I repeated this for a few minutes and it eventually started.
My error was not getting this looked at. It's been running fine since except for today. I went to start it and everything was dead. My odometer would come back after about 10 seconds....but as soon as i would apply power to anything, everything would shut off. Every once in a while the gauges would dance as well. It's pretty dead in the water until i get it towed.
Is my best bet to keep checking all the grounding?
Any suggestions or probable causes/answers would be much appreciated.
