Regulator removal wiring issues

I am installing a CS alternator in my 67 chevelle. the alternator has the big Bat terminal and a plug with 1 red, 1 brown, 1 black wire. I have searched the threads I can't quite find wiring info I need.
I have hooked up the wire from the horn relay to the BAT terminal, then I removed the regulator and hooked up the red that went to the reg. to the red on the plug, then the brown that went to the reg. to the brown on the plug. I have disregarded the blue and white that came from the regulator and the black on the plug is hooked to nothing.
When I start the car it seems to be charging but the warning light stays on.

Two other questions. What is the relay for in the choke system and where do I hook my volt meter to test for proper charging.

Thanks

Doc here

Here ya go..

Are you sure it is a CS series not an SI series..From your description it sounds like an SI..How many terminals do you have under the side/top plug?



You MAY have to extend a power wire to the horn relay If you moved it.. (depending upon how wired or molested in past ) for full function of circuits there..keep that in the back of your mind to check also.

This is the CS..


Happy & Safe Labor Day!!!!!

re:

It is for sure the CS model It has the SLFP plug with 4 posts but 3 wires, red, brown, black, I have tried connecting the red to the BAT post with the BAT wire, the brown to the old blue wire and the black to nothing. but the GEN light is still on.

I am lost

i have a question,


im going to be making the same upgrade to my 66 impala and was looking over my diagram and harness. i have the same setup that doc posted in the diagram with the 4 wires and the same colors my question is im not familiar with this slfp plug.... is that the plug on your car ? the regular alt should have the three wires as shown in the diagram.


as for the gen light, i thought that the brown wire neded to be connected witch IS the gen light feed im assuming that the plug thats on your car is black instead of blue as in the diagram.

i might be completely misreading whats being said but outside of the diagram (witch i understand) im a not sure about the other stuff.

Doc here,

First off, Which Alternator do you have? The CS or SI series?

The SI series will not have the SFLP terminals on it..It will have Batt, 1 & 2 and a ground lug.

The CS series will have the SFLP terminals under another plug on the alternator (which may only have 3 wires in evidence) , you pull that plug and the SFLP terminals are revealed.

If you have the SI series, follow the 12 SI diagram..above.

If you have the CS series, Follow the CS Diagram (the one in the box) above..

Which is yours?

i havent purchased it yet, the car is still completely apart i'm just trying to plan things out ahead.

im assuming that the si model is the older version and the cs is the late model alt for the newer cars and if thats the case i think im all set now that helped clarify it thanks.
