    Exclamation New Jeep. Need electrical help!

    I just got my 1987 XJ last month and am having the worst trouble with the electrical system. The brakes lights, hazards, and dash are out, and keep blowing fuses. I'm having trouble locating the short. I found that the light switch is zapped too, so I used the direct line from that to bypass the switch and connected it strait to the brake line (the dark blue one in my case) and it heats up real quick indicating a short. I started tracking the problem back starting with the passenger side brake light cluster, and dissconnected my way all the way back to the dash. (each time testing it to see if it still heats up) I have narrowed it down to the driver side between the driver brake light and the bundle at the bottom of the driver side door, but I can't seem to find any sign of a short. Most of the wires that run up and down the side are covered with electrical tape, and I'm having to take a lot of stuff apart to get to them. I've never done anything like this and I'm starting to get in over my head now. I was talking to OlneyJeeps, but he just had back surgery and we should all send him a get well message! He has been a tremendous help. I really want to get this on the road in the next week, but I need some guidance. If anyone can assist me, I would really appreciate it.

    did you make sure you have a good ground? without one it will back track on one of the other power wires from another light.

    Which one would be the ground. There are two blue wires that I have identified as my brake light wires that go to the light switch. I cut them appart and found that only one heats up when patched to the battery.

    you will be a lot better off spending the money on a chilton manual or similar to help you trace down wires... the way you are doing it is going to burn something. each time that wire gets hot from the resistance you are compounding the problems.

    Get a voltohmmeter and test the wires or geta test light. or you could get a power probe for $180.some manualforwireing harness. you will cause more problems touching wire together then its worth hopefully wont burn the whole truck down.

    i completely agree with getting schematics for the wiring,,you could be chasing this shorting problem down for weeks and compound the problems,,,i have spent countless nights troubleshooting issues that seem to "move around" appear and disappear, etc...and then like PFM its fixed because of vibration ...

    to me its bad sign when you are looking at a bunch of same colored wires with a ton of tape on them serving as temporary crappy insulation..sure electrical tape works but not for the entire system ...

    im quite sure someone in this forum as a Chiltons or Haynes Repair Manual you could borrow...if not, heres an option:

    have you tried pulling the bulbs in the rear taillights?
    Tires are like boobs. They always look big until you have played with them for a while. Then you just want a bigger set ...

    Well, that brings me to problem #2. I was hoping to solve this problem before I registered the jeep. (it's apart in the garage with no tags)

    So, I gather you got this Jeep for a real good deal? ...maybe too good to be true kinda deal? ... and i thought my Jeep was having problems (which it is, and many since I got it this past October (and supposedly it was CarFax one owner approved -- which gave me a false sense of security) --, . If it makes you feel any better, I think I've actually had my Jeep for a grand total of 3 months of the past 7 with all of its time in the shop.

    Hmm, so you need someone to come over to your place and troubleshoot this issue because its not street legal and you cant get it registered because you need to pass emissions? Schematics = a surefire headache + tons of hours of frustration ,, Ill try to find a manual and troubleshoot remotely...

    Yeah, I still think I got a good deal, I just have to do some work before it all comes together. It's a low miler with a d44 in the back so I'm willing to put some BS&T into it. I'm just a moron when it comes to electrical problems.
