Trying to figure out what is wrong with my 1988 GTA. The battery will die overnight.

I have found that it is one of the 30amp circuit breakers on the fuse panel. The only way I found this was due to how hot it was.

I have also found that the power door locks are not working any longer. Is there something that could be drawing power from them not working?

I can't get the breaker plugged back in because of how bad it sparks when I attempt to plug it in.
