6.2 alternator conversion

[82scottsdale62]

Hey guys. I have an 82 Scottsdale with the 6.2. I am converting it to serpentine belt using parts off of a 2000 c3500 6.5.

My question is what pigtail adapter and resister do you guys recommend for the newer style alternator?

be really helpful if you showed us.

Based on what i found qiuckly, the 2000 detroit had 3 alternator family options

are you using the alternator to run a tachometer? one of them Will not work for that

if your alternator has a fan on the outside, it takes the middle one most likely
If its 2 pin on the outside fan, it should match your wiring now

if you have 4 pin and internal fan, then you need the top one. Mind you, the top one is a CS130-D , the CS130-D was improved upon with the AD230/AD244, which are electrcially the same and connector, but much better reliability, youd have to source one that would fit , which i dont know.
Heres a alternator that would work thats an AD244, but it would only work if you have a 140amp donor , I think. i might be wrong. ACDelco 335-1092
The duramax, in 2001, supposedly uses that alternator ,meaning that while you can use the donors alt, at least be planned to replace it with a superior unit if it dies

I am not currently, but I might someday in the future

That's the one.

I apologize. I didn't realize there were so many types of alternator they ran in that year.

Mine is a new reman.

Here's a couple Pics

that there is a 105 amp CS130D
If you wanted a larger output youd need to either use a AD244 or a CS144 which only the AD244 has the same connector here as the CS130d, the cs144 has the 4 pin but shaped differently
If you want to use your alternator for a tach, do not remove the P terminal from the connector you buy, P is one of the two outer wires. infact, if i were you, id personally keep 3 wires, you can ommit the F terminal if your PCM cant make us of that wire. But using your "S" and "P" terminals are helpful, your "L" terminal is your exciting wire. you can buy a conversion harness that adapts what you have now to that connector if youd prefer, youd eventually need to switch to the kind I showed you in the ac delco listings above

one example
This can be used till your ready to run a sense wire and a tach wire

And also.
I dont remember the diameter of the pulley for the alternator that drives the tach signal so be sure that if You have the alternator that came with the donor bracket that You measure both pulleys.
If one pulley is larger than install that pulley onto Your new alternator as the reman alternators seems to always come with a smaller pulley and that scre ws with the tach signal.
If You do have the larger pulley and You are not going to be using the tach signal feature, send me that pulley.
I didnt realize there was a diameter difference and I let the pulley that was on my alternator go in with the core. It may too have been the smaller pulley:

Also, if @Frankenchevy got a gas burb, and if You would like the newer FFM fuel filter system let Me know.
I have a good spare unit setting on the bench. It does have a new seal kit with it.

That one in your link doesn't use a sense wire? I thought the two that HAD to be used were sense and excite?

You may have to explain this to me like I'm stupid, because alternators are kinda magic voodoo to me still.
