    OK, so I was swapping out my old alternator. I forgot to unhook the battery (stupid me!!!). I arced the old alternator when I was taking off one of the wires. I swapped in my new alternator, replaced the battery fuse, and it ran very well for about a day. I was sitting in line at the bank drive through. It died. I replaced it again, it blew immediately. I replaced it a 3rd time, this time left the battery disconnected for about 10 min, replaced the fuse, then hooked the battery up, blew as soon as i connected the battery. The guy at the auto parts store told me it would probably be $65-80/hour w/ a 2 hour min. to find the problem.
    Do any of you guys have a clue what it could be. If I F'ed it up, why did it take a day to rear it's ugly head? Could it be an ECU prob.? My car is a 90 hf crx by the way. How much would you guys estimate the cost? Help in anyway would be appreciated. Thank you for your help in advance.

    sounds like during the arc you melted a wire, and its grounding out somewhere.
