I have a 1997 integra LS. Yesterday I drove to work radio/Clock worked great. As I got to work there was a sqealing in the speakers. I shut off the car and went into work. I got out of work started the car and the clock/radio didnt work and the ABS light was off(usually on). I started checking fuses there is a fuse under the hood called back up that was blown. Replaced the 7.5Amp fuse last night. This morning I figured I would check the head unit wiring to make sure no exposed wires. There was a few of them so I retaped everything. I drove the car and the fuse blew again with no head unit connected. Any one know what the "back up" fuse is connected too??
