Alternator Compatability

[05Yukon]

Its attached to the alternator. If you look at it you can see it. I believe there is a plug on it also that is connected to the computers to tell it what to do.

whatever yal do, do not expect a smaller pulley on aftermarket high output alternator help out for long, everyone i know with a smaller pulley on a high output alternator had problems with the alternator going out alot faster than just having a regular pulley on there

thanks for the heads up. ran the alt for 4 years without a failing issue....so far, but now it's sat for 8 months in the attic collecting dust. i'm getting the itch to install the system into the yd...just have to find/build a box for my 3 treo tsx 10's or decide to get another one and go 4.....and if this alt won't work then i'll be selling it and finding one that is compatible.

I'll scoop it from you if you're not gonna use it, trying to make the nastiest charging system on my truck so the voltage doesn't drop when my efans both kick on.

I know it will work for a 99-02 FSC or FSG. It should in turn work for a 2000-2004 Hoe or Kon, but from what I've been told in this thread it won't work for 05-06 Hoe/Kons.

coopiesb has 1st dibs on it, but will pass it to you if he changes his mind. I really have been too lazy to just call Excessive and see if he will help/work with me to make it compatible, if possible. That is an option I will likely pursue when/if I ever get around to doing the install...lol. This ** alt will require your engine idle to be at 750 rpm or higher to charge at idle...fyi. BB can handle that end for anyone that would purchase it at the time they get a tune/retune.
