Can someone tell me if I fried my radio. Left my lights on and killed my battery, had a young guy in our warehouse jump me off and he connected the cables backwards and I turned the key to try and start it and it arced at the battery, now no power to radio, everything else works. I replaced the 5 amp fuse the manual said was radio start but no luck. I put this in the wrong section. Sorry 2007 f150.

5 amp fuse is way to small for the radio, i bet there is another.

Hmm are you sure it wasn't you that did it...

Anyways it's very possibly you have a short on your constant wire for the radio or even more possible the switched/RAP is shorted. Best to check out the voltage and continuity of the circuits then get back to use before we can have a verdict.

Nope, it's not too small. It's fuse #7, a 5 amp mini fuse that feeds the radio.

May be fried, and yes, That is the correct fuse

have you checked to see if your getting power up to the fuse?
if you are , but not at the plug on the back of the radio, at lest that makes things easy to splice a new wire in.
also make sure its not the ground, that's at fault. good luck.

i figured the radio would atleast have a 20 amp fuse.

Friend of mine worked at a Western Auto store back in the 70s and he did that
to a customers car and it fried all the electrical.
