    I installed an aftermarket radio in my jeep, while installing I touched the ground wire to the power wire and created a little spark while the car was hot. The radio won't turn on and seems like it's not getting any power, I put a different radio in thinking I short circuited my new radio but this one still seems to not have any power. I figured the problem would have been a fuse but I have checked all over and cannot find anything.... HELP!!!

    Get a tester or test light and see if that wire is hot. Pictures help.

    I have already checked all of the fuses and there hasn't been a blown one. I put the wires on a multi meter but it read nothing.

    There could be a fusible link. Has anything else lost power, or just the radio hot wire. Are you testing it with the key on? Some radios have a hot and a switched hot going to them, most have just a switched hot so if the key is not on it won't register on the meter.

    Is that hot wire a switched hot. If it were me and I was finally frustrated with trying to figure it out, I would find another switched hot and tap into it.

    Dunno if you are still having issues, but if you touched the ground and Ign or memory power lead together you most definitely burned out a fuse. Whether it is the factory fuse or an in-line fuse from the new wiring harness, something is burned. It is always best to find and replace the factory fuse than to tap into a different circuit. If it is in a Cherokee, there is a fuse panel inside the cabin as well as one under the hood. Check them both and find the bad fuse to restore your stereo. ;)
