well i didnt call napa :-/  but the OOO ones were rebuilt and then they put their brand on it.  prob same at napa.  price at O seems high cause i added the core charge, i am keeping my alt for a spare for my g/f tracker.  i guess i will try napa in the AM and see, but i trust my rebuild place better that OOs or NAPAs, will let you know.

Any more thoughts anyone???

I'm keeping the stock alt on mine, It tested out at 69 amps, the stock ones are supposed to last longer in water and mud,something about the chebby's shorting out.  how many lights are you putting on your rig? at 100w ea. thats only 8.3 amps each or so.

only 2 up front on the brush guard that would ever be run on the street.  3 up top on a light bar, but they won't be used very often at all...I already have a pair of air horns and the headlights dim when I hit the horn at night...

Sounds like you need to get a larger battery is all. maybe a gel cell type.

Scottrodmn...where did you go??  I PMed ya about this thread...had a couple more questions.  

Bryan

got 12si 94amp alt from junk yard  $25
new brushes etc, and a nice clean up  $35
new wireing kit from M.A.D. El.  $27
alt bracket from T.T. ... uh, $20 something i think.

waiting on the wires to get here and will try to have a pic or 2 if the weather holds and i can get it put in in 2 weeks or so.

Can't wait to hear how it goes ... let us know if the MAD kit was worth it (as opposed to just fabbing one yourself).

JUST CURIOUS WOULD THE HIGHER AMP ALTERNATER DAMAGE ANY [ELECTRICAL] THING  

The only problem I can think is that you would probably have to run a heavier gauge cable from the alternator to the battery.

same voltage 13.8+-.any higher and you srat damaging

my understanding is that they are about the same 'volts' and the extra amps wont hurt.

this is why i went with the MAD setup, since it is really for V8 cars, looks really heavy duty...... still wainting i hate waiting

i like the pics of the brackets. I just got my T.T. gm bracket today WOW what service and the bracket looks better then stock. What bracket is being shown in the pic for the upper adjuster? The alt that i have is a monster. My stock upper bracket won't fit at all. I picked this alt up from a speed shop that is closing. they mostly did camaro and corvettes. it tested perfect and at 97 amp my little sami should do just fine.

The airhorn's compressor draws somewhere around 20 amps, that's why they usually come with a relay and instructions to wire them through a relay so you don't blowup the stock horn wiring. That big of an amp draw can't help but dim the lights momentarily and it's so quick that by the time the alternator catches up, the load is gone...

I have looked for an alternator for about a month now.  Never found a $40-50 price!
Mostly $79-129 plus a $30 core charge.   I checked some of the cars and trucks mentioned on Autozone on line.  They even want a core charge on an ALL NEW unit!

At that price, might buy the Petro kit.

Any one got a rebuilder in their area?  They could stock some and get some bussiness from all of us trying to find one.  I prefer the CS130 because someone said it was smaller than the 12?
I am also worried about the top mount, I think it should be moved from the small stud on the water pump up to those big bolts on the head?

I have put a lager batery in that fills the whole space (24 or 25 Group?).  Eventually I might put my Ham radio and possibly a wench in the Sammy.

Thanks for the thread!
