88-95 alternator type?
 

Is the alternator on the 88-95 half tons a CS 130 or a CS 144, and are they the same case?

Re: 88-95 alternator type?
 

Between 1988 and 1995 there are many different alternators on these trucks. It depends on the equipment package / how many accessories the vehicle has as to which alternator is used on it. They are not al the same size and some are mounted differently.

Use the RPO code in the glove box to identify which alternator it has.

K64 - GENERATOR 115 AMP
K65 - GENERATOR 105 AMP, DUAL

K76 - GENERATOR 61 AMP
K77 - GENERATOR 56 AMP
K79 - GENERATOR 42 AMP
K81 - GENERATOR 66 AMP
K82 - GENERATOR 75 AMP
K83 - GENERATOR 35 AMP
K85 - GENERATOR 37 AMP
K88 - GENERATOR 45 AMP
K89 - GENERATOR 50 AMP
K90 - GENERATOR 108 AMP
K91 - GENERATOR 65 AMP

K93 - GENERATOR 32 AMP
K96 - GENERATOR 55 AMP, BUILT-IN REGULATOR

Cool, thanks.

Re: 88-95 alternator type?
 

I'm confused on this as well. The RPO code tells you the amperage of the alternator but does not tell you the model of the alternator. I have a 1991 Suburban V1500 with a 5.7 TBI engine. I have the RPO code of K60 (100 amp) but is it the CS130 or CS144....????

Re: 88-95 alternator type?
 

Just look at the case they are distinctly different.

Re: 88-95 alternator type?
 

Will either of the two fit a 1991 Suburban with a 5.7 engine....???

Re: 88-95 alternator type?
 

With some minor modification, either one will fit.

Re: 88-95 alternator type?
 

To mount the CS144 in the CS130 mount you need the bracket that cradles the CS144 alt in the CS130 mounting space. I have this on my '89.

Re: 88-95 alternator type?
 

Anyone have a picture of said mount? Is this something I can fabricate or purchase?
