Another CS altenator question

810 Views 3 Replies 3 Participants Last post by  72SSAbody
I've been searching at the 'yards and online for a CS altenator (the junkyard dog comes out
) and I noticed on some HD trucks and vans from GM you could get a 165 amp CS alt.

Has anyone run these? Or is this just overkill from the 105amp version?

I'm running my dual windstar fans, MSD box and an amp for my stereo.

Can anyone recommend what gauge wire to run off the altenator for that amperage?

I'm an ME in training so I don't remember too much from my circuits classes other than V=IR
to save my life!

I just got a NEW CS144 140 amp from a 95 Caddie for $50 on Ebay. There are a lot of them on there, just be patient. The CS144 is the biggest, most powerful, most reliable alt that GM makes. It might take a little tweeking on the brackets to make it fit. The CS130 is smaller, and will work fine, but for the price of the 144, no contest.
