    Does anyone know how or have a schematic to upgrade the A/C Delco 63 or 65 amp alternators to 100 amp. I heard that it just adding diodes? Just trying to keep you guys thinking, Rick.

    It's more than just diodes. J.C. Whitney sells the kit for about $33
    with a discription of the parts. Hope this helps

    :nod: check with the local parts store for a possible ambulance or heavy duty version being available. I got mine for a K-30 camper/ ambulance. Rebuilt/ bolt in, for less than 100 bucks. Just make sure its "clocked" the right way,and make sure you use the same pulley you had on the old alternator. Hope this helps.

    Try this place........


    or, if you've got some $$$, try a Leece-Neville. They're expensive, but 140amp L/N will put out 200amp without getting hot.

    just my $.02

    Good luck.....

    If your going to upgrade,get a complete unit.All the components are matched together to work properly.

    To get a decent alternator,you need a bigger case style.Swapping on something different is the only way to get a high output alternator that will put out what it's rated at.
