I unplugged my security light and my battery. Plugged it back in now it doesnt turn on. I have an aftermarket radio. Checked the fuse and it was fine. Any help would be appreciated. NEED MY TUNES

 

well first check both fuses(on the radio and the fuse box) then check the fuse in the engine bay on the left to the middle black fuse. check your ground the wires for power are i think blue red and a yellow one .good luck

 

Some aftermarket radios have a reset button behind the faceplate that requires it to be pressed after power is cut to the unit.
