Alternator ID

[kennyw]

I am trying to ID the alternator on the right. It is approx. the same size as the stock 12SI that came out of my '83 K20 (will bolt right in place after a pulley swap). It is stamped with 120A on the front.

I am way out of practice but I will try

CS130?

And I dont remember the wiring

Pics don't look like a match... but after a little more searching its looking like a CS144 now.

It is definitely a CS alternator, but I am not certain which model. I believe you are right about the CS144.

CS144's were supposed to all have the plastic fan, and be quite a bit larger than the CS130's. I could measure mine up or get ##'s tomorrow, I have both CS130 and CS144 alts here.

That is a CS130, same thing on my 89 blazer and IIRC were used up until around 1992-1993 then came the CS144.

I just put a CS144 in and that does not look like one...too small
