I have a 1986-1996 GM CS-130 alternator which has a BAT post and four little terminals marked "S", "F", "L", "P". Does anybody out there in Hot Rod land know what these pins do? What do the letters stand for?

I read the alternator stuff on this site and I got a bunch of good info, thanks.... but, where is the nitty-gritty on CS-130 pins?

Thanks to all who read this, may your alternators alternate and your diodes diode, and all that there electric talk.

CS 130

Doc here:

Here is the terminal layout for your install...

S - connect this right to the "+" on the Alt. with a ring terminal
F - Not needed
L - Connect to 12V source with a 3-4 Watt bulb in the circuit
P - Not used

This was a conversion actually for a jeep...I think
(therefore I have headaches...)and this is only a guess..

the terminals are S = self excitation, F = field,L= lamp, P= your guess is as good as mine....

Hope it helps!

Doc :pimp:

Thanks for the info Doc! I thought this alternator was going to be simple to hook up, is after all a ONE WIRE alternator! But, turns out there is them other four wires too... Oh well, I am getting an education.

I found another place, in case anybody else is wondering about the guts of their alternator, (the GM CS type). This place has a wiring diagram for it and a few pages on trouble shooting etc.

Thanks again Doc.
