cs130 Alternator
I have a 67 Camero with a new GM serpentine system. It came with the CS 130 Alternator but no plug so I know have a problem as to how to wire up the system. Can anyone help?

It's basicly like the one you had, if you had converted to a internal regulator. If you haven't converted, it's a little more complicated but still easy to do. I've attached diagrams.

Most of the connectors for the CS alternators are four wire but you will only use two of them and the wiring is the same as the SI.

S = a heavy gauge wire to the battery supply (horn relay)
F = not used
L = a small gauge wire that comes from the idiot light and energizes the alternator
P = not used

Hope this helps you out

Actually, the F terminal is used if you DON'T have an idiot light. The alternator has a built-in resistor connected to this terminal that replaces the resistance of the idiot light. When the F terminal is connected to a key-switched 12V source, this will also energize the alternator. Use this terminal instead of the L terminal if you have a voltmeter instead of an idiot light. Be sure to use only one of the two (either the F or L terminal), not both.

You are correct, but I assumed he had a stock dash and a idiot light.
