I hooked up my battery backwards upon reinstallation after removing it when it went dead. I fried 2 sets of jumper cables this way before I realized it. I replaced the battery (Optima Red Top) and the ZJ seems to be running fine now. I believe the old one was damaged because it wouldn't hold a charge. Under acceleration, the engine would stutter (I believe because the battery couldn't adequately power the ignition components.
Now I'm chasing electrical gremlins. Everything seems to be fine now, except that my radio (it's a sony headunit) won't turn on. I suspected the ECU, but if it was that, then technically nothing would be functioning. Maybe I just fried the radio? The battery gauge on the instrument cluster stays at 11.5.
