Nothing works, please help.

Okay, so i own an 1990 240SX fastback. I have a KA24E and well a few days ago my friend and i were messing around with it, and i had the battery out and everything, and i told him to put the battery back in, and he did but he put it in backwards, so the negative wire went on the positive terminal and vice versa. I then noticed that nothing worked, no power options, the headlights and tail lights work and same with brake lights, but the dash lights dont, and the radio doesnt, also the seatbelts and windows. I know it blew a fuse probably, but what fuse did it blow. Please help me i just got it running and i dont want to drive it without power options and lights.

Thanks in advance

Start checking all fuses and relays. Start by the fuses/relay under the hood by the battery. After that move to under the kickpanel on the driverside. You may have to go to the junkyard to find some spares relays, some are pretty expensive.

You blew the 80A Alt. fuse
