I have searched google and this web site up and down and everything I have done hasn't worked.
91 xj 4.0l
As the title says I have no power to my gauges(they don't work or the lights) or any of my running lights. It keeps poping fuses for the gauges.
I had a amp and new door components installed the other day. Picked it up and I realized my issues. I traced the power wire for the amp thru a grommet on the fire wall. (I took dash apart to make sure the wires weren't damaged or cut and they werent). Pulled radio out and checked the illumination wire, that's good to go. I bought and a new headlight switch installed put new fuse in and it still poped. I have looked over the harness for about 2 hrs this afternoon and found nothing. So if you guys can please share your experience as to what you have done would be great

Well i might be wrong but if you keep popping fuses, you have a short somewhere....

With some more patience your gonna have to trace the wires; it can be a wire touching metal, a bad connection, grounds touching wires. Took me over a week to find my problem when i couldn't get the fuel pump to prime and run

 

I know there is a short somewhere just can't find it. Where was your short fornthe fuel pump at?

 

I am pretty sure your jeep probably has the same connectors. But under or close by the fuse block under the driver side panel are (2) 10 pin connectors ( i believe they are 10 pin), the gray connector had melted spots from the wiring to connector. I can not find a picture at this time showing it, but i do have this one... Hope it helps, as well i did cruiser54 tips and tricks for a new ground for the fuel pump.

 

If the wiring looks good, start pulling connectors and look for burnt pins, like shown. Check the connectors for any corrosion. Corrosion increases the resistance, and that resistance builds heat. The heat wicks up the wiring and the fuse pops. Same can happen with a loose connection, so look for any pins that have backed themselves out. Knowing which components use that same fuse can help narrow things down as well as the issue could be the component itself, and not the wiring leading to it. Check those connections also.
