i dont know how i did this, or whati was thinking... it was 3 in the morning.. but i hooked up the battery backwards on my rx7.... it made this really loud sound... I blew my main 80Amp fuse....

i replaced it and somehow after charging the battery up again she fired right up...

the only damage now is the radio, clock and interior lights do not work...

I tried replacing the fuse but when i put in a new fuse it burns out immediately ... my guess is there's a short or I bured something out...

the one strange thing was when i remmoved the fuse box, the fuse correlating to the radio was "sticking out" and it was a 20 AMP fuse and not the 7.5 as the label on the box said it should be.

has any matched my level of stupidness and gone through this???

 

I'd start by disconnecting the radio.
The see if the fuse holds.
The previous owner may have been trying to run a high power stereo of the original radio circuit.

Good luck...

 

That fuse "sticks out" normally.
