    Default Can anyone tell me any information on this alternator(pictures)

    I came across this alternator in the shop today and it appears to be brand new was still wrapped in plastic when i found it, no one claims it or knows what it is. If I can find out how many amps it is i may consider putting it on my silverado as the current one is almost too small.

    I say just take it to autozone or a mechanic and have them bench test it and they will tell you its output

    Can't help and I can't remember the last time I saw a V belt drive on an alternator.

    Times have changed, I was thinking the same thing!

    I would guess buy the size and being a single groove pulley, that its likely less than would typically be a double pulley if it was bigger than 100A.
