    I have heard of running 2 alts but usually you need to find another bracket or fab up your own for the left side of the motor and really why bother. I would go w/ a dual battery set up and run one of the Huge alt's from Wrangler. Just my $.02 plus then you can keep your ac [​IMG]

    I'm not a very big Powermaster fan right now. I got a 140 amp from them and it has been a PIA. They sent me a V belt style one and when I called they said switch the pulleys to the semi-serp style you have now. Well it doesn't take a rocket scientist to see the V belt pulley is a lot smaller then my serp pulley so thus the alt turns slower. Only place this makes a problem is at idle it only keeps the sytem going a about 12,4 volts... when you take the idle rpm up a few hunreded rpms to 800 or so it is ok and puts out enough voltage. So now I'm stuck trying to find a pulley set for the V-belt style or hoping Wrangler makes an overdriven pulley in my style belt. Other then that no problems... just kinda annoyed w/ them at the moment LOL [​IMG]

    I got the Wrangler 140A with a new pulley, and charging wire kit..(0/1 ga...looks like jumper cable).....fixin' to add another battery when I feel energetic enough.....you can get Alts up to about 200A.....I've got about $200 in my setup.....JD

    Stuck?...Hell no..I still got some gas left..

    Absolutely no reason or need to. I too have the 140 amp WranglerNW model with the direct charge (massive) cable for over 3 years now and it flat kicks butt.
