Yesterday I accidently hooked my positive battery terminal to the negative and the negative to the positive, i blew up my amp fuse and my main fuse, car wasn't running, i got those two replaced but now my cd player doesn't turn on, the fuse under the driver side seems good, anyone know what happened?

 

iether the deck got fried like mine did, or the fuse in the deck got fried.
Take you deck (cd player) out and check to see if the fuse is still good.
I know I had to send my deck back to JVC to get it fixed.
If your lucky its just the fuse, and your deck isn't fried.

 

Does the fuse "seem good" or is it good? Test it and find out before pulling your deck.
