Craig,

Thanks for the kind comments.

To find CS-130D applications, go to:

http://www.knappsautoelectric.com/

<http://www.knappsautoelectric.com/>Select Products/Delco
Generators/CS-130D.

They've got lots of other good info there also. Until I started trying to
find a more modern, less electrically noisy alternator to install with my
Cad 500 & EFI, I didn't realize how much better units are available to
easily replace our old ones. The CS-130 and CS-144 are apparently direct
replacements for the SI-series in the GMC. The CS130D is a further
improvement on the CS-130, more reliable and even less noisy (uses avalanche
diodes for spike suppression). However, it is not a direct, bolt in
replacement for the SI because it's much smaller. Even with its 100-105A
output, it's about 1/2 the size of the SI-, and there are the usual
aftermarket upgrades, which I've seen advertised as offering up to 200A
output. The output is very high at low RPMs too.

As you'll see at Knapps, there are at least 9 different physical
arrangements of the mounting and connection arrangements available. Mine,
from a '99 S-10 Blazer, is #8231. There may be better mounting
arrangements, but this one worked OK for me.
