its the fuse that releases your shifter and emergency flashers and I think brake lights,but those two for sure,also my radio don't work and when the car is off my radio makes a cracking sound threw the speakers like it wants to go on,but like I said my key is off,maybe my radio has a short causing my no.11 fuse to burn out,also my battery sparks when I put on the cables??something shorting out ???>HELP
