I am in process of changing radios on my car and long story short a wire touched something and sparked. The radio will not turn on and I checked fuses, the ground, switched power wire, and constant power wire. I have no power on my constant power wire and I need to know what fuse that is and what else is on that circuit. The fuse labeled radio in the glove box fuse box checked out and the fuses at the under hood fuse box tested good. It is weird because everything else on the car still seems to work except the radio. I am going to do some more checking tomorrow and it all else fail I can run a new constant wire with a inline fuse and call it a day.
