    I would like to upgrade my stock 63 amp unit to a high output unit. I do not want to spend a fortune though. I see 4WPW has "Powermaster" units that are 140 amps, for less than $200. Would this be an ok unit, or is there something else I should consider? /forums/images/graemlins/1zhelp.gif

    JEGS sells hi output 1-wire amps in different ratings.
    I got a 100 amp 1-wire unit for $90. Works great. If you need more amperage, they sell those too.

    Just out of curiousity, how does a one wire altenator work? I have wondered this for a while, my current unit has a plug with 2 wires and the wire off the back.

    Also...how many amps is enough? I currently do not run much, no stereo or winch, some off-road lights. I would like to upgrade to something that would be powerful enough once I do add a winch, etc.

    A one wire alt. Uses a self exciting regulator. It will "turn on" when engine RPM is about 1500 to 2000. It is the same as a regular alt. with a diffrent regulator is all. They sell the regulators at NAPA, if you ever wanted to convert one to this set-up.
    I rember there being a rebuild kit for High amp alt. somewhere. I'll have to rember that later. Anyhow I use a factory 94 amp. GM alt in mine and never needed more. I got it from a place in Bellevue, R&L they have starters and alt, generators even. /forums/images/graemlins/grin.gif

    I used to rebuild Altenators for a living. The 7127 (GM inturnal reglator) is very easy. You should be able to find an Altenator rebuild shop in your area that could put together a High Amp unit for you. We used to sell them for $68.00 or build yours up for $25.00 if memory is correct. I'd look into that befor buying a new unit.

    At this point it would be easier for me to order a new one and keep the one I have now as a spare. Not much time right now to find a shop and take in etc, thanks for the suggestion though.

    Think Im gonna go with that one too. Seems to be the best price I can find and sounds to be of decent quality. Thanks

    I got mine from the local parts store for a 1 ton chevy with BB and all the power stuff. Stock is 95 amps. Around $80 bucks with a lifetime warranty.
