ok, i'm going insane trying to figure this out. i replaced the water pump and in the process I disconnected the battery, removed the alternator then replaced the water pump. I put the alt back on and the battery back in. when i hooked up the pos and neg terminals the pos started to spark(kind of like when you're jumping a car) and then the sparking stopped. so i started the car and it started up just fine, but i had no interior lights, no tack, no temp gauge etc. I checked the fuses and it ended up being the battery fuse under the hood. so i replaced that and it instantly blew again.

now in the process of this i determined that when the wire for the alternator was hooked up it was blowing fuses, however when i took the wire off the fuse was fine and NO sparking occured at all.

PLEASE help me because i'm stumped. could it be my alternator? or a ground. I've tried checking the grounds and they seem fine. any advice or input would be so helpful.

thanks

Something may have happened to the alternator when it was removed. Somehow the stator became grounded to the case, which would create a short and the problem you describe. Try swapping in another new or used alternator.
