Hey guys, I know there might already be a forum about this but I haven't been able to locate it myself. I accidentally hooked a jumper box into my 1978 280z backwards and now the fuel pump as well as the dummy light for the alternator both stay on when the battery is connected. I thought it could be a fried ignition switch but even when I unplugged it they both stayed on. The car fires up and idles perfectly. If anyone could help me out I'd really appreciate it.
