I hooked up my battery backwards and my radio no longer works. I think I have checked all of the fuses. Could I have blown the head unit? Any suggestions would be great!!

Re: Hooked up battery backwards...No More Radio!!

well, it sure could have but more info could be helpful. With not knowing specifics its tough to diagnose. I would check to see if you have power going to the radio-guessing a red or possibly yellow wire, should have at least one wire with 12v going to it. If not, you may have missed a fuse somewhere. When you check for power, use the ground going to the rear of the radio to insure it is good also. If power and ground to the radio is ok, looks like the radio is toast. Not sure if you are going through an amp-that changes everything. Sometimes there is a fuse that plugs right in to the rear of the radio. If its not a factory radio, many hands could have wired it many ways. If all you lost is the radio, consider yourself lucky-computers hate being wired backward:facepalm: . Im sure someone with better info will chime in soon. Welcome to the forums

My radio didn't work (wouldn't power up) from the PO. I removed the entire radio to troubleshoot it on a bench. Well, there was a little plastic black cover on the back plate of the radio, next to the wiring harness. I didn't even see it when the radio was installed in the boat (it was so inconspicuous), and I wasn't positive that a fuse could even fit under that little black plastic cover. But, sure enough, there was a mini blade fuse under the cover -- - radio works just fine! Not my usual luck.

I'd first check for power getting to the radio (as suggested) and then try to power it up on a bench - you can see a lot more on a bench than from inside the console.
