hey, so i was changing my alternator and forgot to disconnect the negative to the battery and i had it all hooked up except for the "B" terminal and it touched the actually alternator and sparked really big and after the the battery guage went back down to the bottom white mark and when i tried to use the radio, power windows and the AC the guage went all the way down to the red and i couldnt get it to start after that, had to keep jump starting it, im tryin to figure out if i kinda revesed the flow of the diodes of the polarity, cause everything is hooked up to the ecu. much needed help would be greatly appreciated.
