    Just my luck....my Alternator went out Sunday, so I had to buy a dang battery to get me home....Monday evening after work, even before I have a chance to get into my Alternator prob, I find a brand spanking new 4 Wheel Off Road mag in my mailbox...with an article on Wrangler Hi Amp alternators.....am I a lucky guy or what? so anyways, I ordered me up a new Wrangler alternator 135amp with a new pully, and 1/0 gauge charging wire upgrade ($225 amp, $25 pulley, $57 wire upgrade, $22 shipping).....I'm hoping it gets here Fri so I can put it all in this weekend...I'll try to take a few pics and let y'all know how it turns out....if I get really energetic, I may even finally get around to installing my ORD steering brace and take pics of that also......I'm just sorta peeved that I had to blow money on a dang battery I don't really want or need.....if any of y'all have any experience with this type of alternator set up (as in how expensive is it when it goes tits up), I'd be happy to hear about it....Thanks, JD

    I'm at 10th and Plum....10 miles from nowhere, and Plum out in the sticks....Stuck?...Hell no..I still got some gas left..

    Good luck on the alt. I heard those are very good. Now with the other battery, just get a battery isolator kit and you have a dual battery system [​IMG].

    I'm thinking about that one or a 140 amp Powermaster alt... anyone know anything about the powermasters? Is the pulley a special one or can you just use the old one? Looks like it is time for me to hit the newstand [​IMG]

    A buddy of mine got a hi-amp altenator because he has such a big stereo in it he was going through altenators real bad. He's had his for 3 or 4 years and hasn't had a single problem with it.

    Imagine a cowgirl twirling a rope.

    CaptCrunch,

    Yes, I have the Powermaster 140 amp alternator, and I love it! It performs awesome, powers all my lights, stereo, winch, etc with no problem. It was actually tested (all Powermasters are tested at the factory and they give you the printout of its performance) and it is actually putting out 156 amps at 2000 rpm, and 91 at 750 rpm! Considering most of the stock alts put out anywhere from 40-60 amps at idle, that is a great increase. And their price is not as high as the Wranglers. I got mine here from work...if you, or anyone else is interested in one, email me, I can get you a deal on one!

    Just an FYI
    I have a 120amp atl that I got from one of thoes "AutoElectric" shops. Basically all they do is take a stock alt and replace all the guts to make it a higher output alt. I also asked them if the had heavyduty type bearings and cooling fan and they said yes, all in all they charged me 120 bucks for a heavy duty 120 amp alt and that was back in 96. It keeps my dual Optimas primed and ready to ROCK!

    Just a dumb question. Is that the RPM of the alt. or the motor?

    Good choice on the Wrangler, I got one. The good the about them is the front bearing. They are HEAVY-DUTY, and you can get replacements at any NAPA Store. No more GM's for me! GOPHERKILLER
