Ok, got my TT GM alternator bracket.  I know it's designed for the 94a 10SI and 12SI alternators.  Just curious what you guys are running on it.  Gonna try to pick one up today or tomorrow.  Also, did you end up fabbing your own top bracket up, or can the stock one be made to work?

Thanks!

I just run the stock kick alternator mine puts out 69 amps and does well under water, I have friends that run two batterys and a chevy alt and they have problems with water and mud, I just run one battery but it is way larger than stock but it runs my warn 6k winch just fine.

and search "gm alternator" here, there is tons of info

I've looked around here to no end.  Even found the 3 pg thread I started quite some time ago.  I was just curious as to how many more people were running one now and if anyone had any tips/part number/applications.

Well mine is still going strong, I have a 105 amp in lil Suzy, The only down side is that it can sap quite a bit of power from the little engine if you have a lot of things running. But that is better than having a alt which can't keep up so discharges the battery.

Definitely so.  That's why I wanted to go ahead and upgrade.  I'm gonna be putting at least 2 if not 4 offroad lights on it, and I have an amp running my speakers instead of the headunit, so I'd rather go ahead and upgrade since I have to replace it anyway...

Just wanted to let everyone know I got the alternator swapped out.  I used a 94a 12SI GM unit.  I'll post the part number at the bottom of this post.  Everything was very straight forward.  There is a 2 wire plug on the back side on the alternator.  You will need the pigtail for this.  I read in one of the articles somewhere how to hook this up.  The red wire I jumped back to the main post on the back of the alternator.  The white wire gets spliced into on of the 2 wires that went into the plug that plugged into the back of the stock alternator.  Evidently the colors changed from year to year on the wires.  Mine was the white wire.  Pick one, doesn't matter which one.  Start by just twisting the wires together and make sure they're not touching anything.  Start the truck.  Now turn the truck off.  If the truck keeps running and doesn't turn off like it should, you have the wrong wire (I picked the black one first. LOL)  IF this happens, just pull the wires apart to kill the truck.  Splice into the other wire and you're golden.  So far, everything is working great.
