If you put a new radio in a 96 Saturn and it worked fine for a month but now won't power on and neither will the old one and you have checked all the fuses what else could it be?

Answer 1

Wiring problems can be time consuming, but the only way to accurately pin-point a problem is to start with the obvious and go from there. I would first do a "bench test" on both radios. Run a positive wire lead,( red wire on radio ), direct to the positive battery post, and a negative wire lead, (black wire on radio), to the negative battery post. This will confirm that the radios are working. If they work, and the radio fuse in the car's fuse panel is good, you probably have a poor ground, which is the black wire coming out of the radio. Try routing the black wire to the chasis or unpainted area on the body. If this still doesn't bring your radio to life, re-route the red positive lead coming out of the radio to another location in the fuse panel,ie.(windshield wiper, heater). Depending on where you route the positive lead, you may get unwanted whistling or wherling noise through your speakers.You also might have to manually shut your radio off everytime you shut the car off, depending on what fuse you use. Just keep trying. Good luck.
