Dang - you type (and I guess search ) faster than I can :yes:Thanks!!! Now where was that tech ref section to explain the wiring...
Here it is...
... Ummmm, we seem to be missing a critical connection here!! The "sensing" wire, which one is that?
The CS does have a sensing wire (it's "S") - but it's just not necessary to wire to remote storage source (battery) for most installations :noway:... If the CS does not have a sensing wire then I wont use it. A one wire alternator may charge the battery, but an alternator is more than a battery charger.
Yup - that's the connector.is this what you're looking for?
I think there's an echo in here SteveI just looked at MAD Electrical and found these part numbers....
GM Dealership Parts Department # 88987962
Most good auto supply houses should have it - @$15 :thumbsup:
AC/Delco #PT1742 (GM #88987962)
I usually cut them off "donor's" at Pick-N-Pull :yes:
S = Charging wire, I'll use the one I have on the 94 amp 12SI
L = Power/Idiot light, I'll use the wire from the 94 amp 12SI
F = ??
P = ??
It was a piece of cake...If I would have known that the CS130 (Napa P/N 1N-4521 $102.04 1991 Chevy 1 ton w/454) was a direct fit I never would have run a 12SI. I had already made all of the mods to bypass the external regulator and was running an aftermarket bracket setup ( http://www.alangrovecomponents.com/S.B.Long_Pump.htm part number 215R-ALT). I have a long water pump if that makes a difference....Anywho, all I had to do was wire in the new plug (Napa P/N VRC191 $10.88), bolt in the CS130 and done!Paulm
Let me know how it goes. I am doing the same thing as you and have had problems. Let me know how you wire it up and if the alt. works well under load. Also do you have v belt or serp?
