I accidentally arced the 12v constant and the ground while trying to close some connectors on my radio harness and now my radio does not even power up and the windshield wiper motor stopped working. No fuses were blown at all, the arc was very small, and there is no smell of burnt wires, WHAT THE HELL IS GOING ON????

So you say that the 25a for the wiper and 15a for the radio are still good? Do all your other access. work? Pwr window, turn sig, heater motor? Obviously they work only with key turn,,,, There is a fusible link B that feeds the ign. switch, in turn feeding the fuse block.

 

Checked all the fuses at the block thrice, all the other accessories work although I didn't check the windows. I read up in my service manual and both the radio and windshield wiper motor are spliced into different grounds. My first guess after checking the fuses and not smelling any burnt wires was a burnt up ignition switch but i arced the constant from the battery. Maybe theres another fuse under the hood some where for that?

 

There is a fuseible link B that comes off the alt. And the other side of alt is Battery. There a 2 fuseible links, so B is a red wire, that feeds the ign switch. I doubt anything is wrong with the ignition switch, but that's the feed for that whole circuit. If you have schematics you'll see what i'm talkin about. If not msg me your email and I'll send that to ya.

 

Wouldn't none of my accessories work then if that was the case?
