I was putting on my EVO O2 housing and the heat shield touched the alternator and it sparked. Thinking it didn't do anything I finished the job. I go to put some tools back in the car when I was done and the dome lights wouldn't come on. Windows won't roll down and power seat won't work. I turn the headlights on and they work so I turn them off, only thing is, they don't turn off! I just pulled the fuse so my battery wouldn't be dead in the morning. I checked the fuses and they are O.K. I don't know what else to do, Any ideas?
