consider using an isolator on that second battery to separate it from your starter battery

sorry i don`t have any way to put a picture on my computer ! but i will ask my sister if she can. okay here goes the relay triggers the alt that charges the stereo batt from the truck acc fuse because these alt have one wire plus the batt wire terminal if you wire that wire straight to the batt the alt will drain the batt (the regulator) see this wire lets the alt know when the batt needs charging .the factory alt charging wire goes through the ignition switch so i wired the relay for the system alt to the ignition so it`s charging only when motor is running.BUT there is no diode big enough to wire between the batt and the alt charging sensor wire.the bat isolator want work because i have two separate charging systems and batteries i will add second batt to the system later under the yukon.NO MORE DIMMING LIGHTS!! reply back fellas

So basically what you're saying is that you're going to have one amp dedicated to the vehicle and starting battery and the other amp/ battery combo for stereo and accessories and set up as seperate charging systems for each.
I gotta see some pics of this, although I'm sure it can work.

I think you mean alternator cargodz? And yes, that's the basic idea, and it will work great!

Check out Mean Green alternators. Very good stuff at a reasonable price. As far as I know, from what I have seen and/or used, all of their alternators are bought stock brand new, and rebuilt. Your local alternator shop can't always find the parts to build up stock alternators, especially for newer cars. Thats where these guys come in. They also do custom work, obviously extra.

How much does each alternator produce?

both alt are the 105 amps i put a smaller pulley on the system alt so it`s spinning faster at idle. i did buy that alt on ebay it was suppose to be a 140 amp took it in for service thought bearings went bad but it was the pulley the hole got bigger they tested 105 i was pissed.later on i will look in to getting one for a 96,97 alt i think it`s 140 amp.i thought that what he meant alternators
