So I finally got the wiring figured out on my subwoofer (that I buggered a while back ) and tried to turn the radio on to check. No juice. Seems the 10amp fuse was blown. But when I replaced the fuse it immediately blew again. And a third one blew. I know electrical gremlins are hard to chase, but I'm wondering if anyone has any ideas where to begin on this? I have no interior lights and no tunes.

Did you install the radio yourself?

Pull the radio out and check the harness. Use a meter to check to see if the red wire is shorted to ground. Check the yellow wire to see if there is still +12V

also the remote wire to the amp could be shorting to chassis ground

depending where u ran the wire, u could've nicked it.....im pretty sure that'll pop the radio fuse (possibly amp fuse tho)...ask me how i kno

No, the entire setup has been in the XJ for years, professionally installed. I swapped the sub box some years ago for the (cubby hole) sub - basically changed out the "enclosure" - and everything still worked fine. But I had to remove the sub when I re-did the interior after flooding. I got the 4 sub wires confused at the time & ignored the radio for a long time. I rarely drive the Jeep anyway. Anyway, I finally straightened out the sub wiring, & that's when I realized that the fuse was bad. Prior to this my interior lighting was out, but I thought that it was because I hadn't properly re-installed my overhead console after re-upholstering. I was planning to fix that anyway. But I now realize that it's all connected.

I can live with it, but as you might guess, wiring is my achilles tendon & I'm afraid the XJ might burn to the ground or something, since there's a short somewhere. So I need to get this fixed.
