radio cuts in and out
this isn't in a jeep, but my girlfriend's radio in her car turns on and off randomly, not corresponding to bumps or movement. i checked the fuse, and it was fine, so i took out the head unit and tested the ground and the two +12 wires with a light bulb, and they have continuous current that doesn't turn on or off. my question is could there be another loose connection somewhere that would cause the radio to shut completely off (including the clock), or are these three wires the only ones that could affect that (besides a broken head unit)? any ideas?
