Delco alternator swapping. SI, CS130, CS130D and AD244

[JRBird]

Good stuff. I swapped a 105 amp cs-130 for a 220 amp ad-244 as well as a big 3 and I never see my voltage come off of 14~ ever! I had to clock the alternator though - because the charging post was sitting right on top of a power steering line. I clocked the rear 90 degrees clockwise ... and it fit like a glove.

I remember in 1989 you could get a rebuilt alternator from AC Delco that was a 130 amp .. I got the part number out of a Hot Rod Magazine article, and there was an AC Delco parts depot right near me. I think I still have it. It was in my 68 Chevelle.

I’ve got the CS144 (early style) in my 89 Cadillac. I think it has the same mount and plug as the CS130. I was putting out over 14 volts at idle. I’m rebuilding mine with new bearings and brushes but it was working. May be another option. Pretty cheap for a Delco unit and puts out 130 amps.

CS144 Takes same plug as CS130 (old) square 4 pigtail.

Delco 30si is the most reliable alternator there is. It has large bearings, no brush or commutator and you can get one over 200A and a self-excited controller that doesn't need the plug at all

This is exactly what I need. I have an 87 blazer 350 and the alternator (2pin)has been swapped to a serpentine belt instead of a v belt . Auto parts store only has serp belt with a 4 pin plug. Should I upgrade to your setup for more juice or buy a a harness from 4to 2 pin. Any suggestions will help.

If I have the battery light in the dash should I use a resistor?

Can you post the link for the adapters please
