CS 130 help...

Just bought a CS 130 alternator and it has the 4 pin plug. I've rear,checked,re-read,and did a search. ullinghairout:

What wire goes where
I would like to do how Wes did the SI. Maybe I'm a lil'slow today (OK,more than normal) .....But I do not want to have to re-wire the whole system.

Re: CS 130 help...

Been trying to get to Mad Electrical site all afternoon...I keep getting a blank page

Thanks for the links though

Re: CS 130 help...

That schematic came from an article I wrote on a proposed method of hooking up CS style alternators with remote sensing. The benefit is keeping the battery well charged while maintaining good system voltage. However, if you have a factory ammeter, it won't work properly in that configuration.

What are you having trouble with specifically? Are you trying to figure out how to retrofit the CS130 alternator into the OEM wiring? Are you essentially looking for the external regulator delete mod? If so, take a look at WES's article if you haven't already. https://www.camaros.net/techref/ftecref14.html It shows exactly how to change the stock wiring for an internally regulator alternator.

Re: CS 130 help...

Dave, yes. I was hoping you'd show

All I want to do is retrofit it and do as Wes showed with the voltage regulator.(no guage,just a idiot light)
SSSoooo... I only use S pin... goes to the bat.terminal on the back and L pin gets the old wire from the old alt. (one w/o power when key is turned) ?
Then the mod. at the ext. volt reg. ? correct ?


I looked through the box and found a schematic for what pin is what.


S pin and battery post hook together.
I pin to idiot light.
L pin to a 300-500 resistor (tied into light) to fuse ingnition switch.
P pin to relay or tach.

I will copy and post later today.

Re: CS 130 help...

You only need to have two wires connected from that modular plug. The L wire is the light wire. It should be brown and it will be hot when the ignition is turned on, but it's being fed via the GEN lamp and a paralell resistor wire under the dash. The other wire you need is the S wire. This wire is for remote sensing. Whatever the S wire is connected to, the internal regulator will attempt to hold that point at a steady regulated voltage. The horn relay would be the best place to connect the S wire to, but most people just connect it to the big red lug on the back.

Re: CS 130 help...

You know...<scratches head>...I don't even know if the "S" wire is hooked up on mine anymore? The charging wire, I think, is where it senses voltage? My battery is in the trunk which really screwed up my whole charging setup.

Re: CS 130 help...

One last question (yea,right )

I have the diode in due to the MSD box... keep or lose it ????

Well,, you installed the diode for engine run on. So if you remove it and the engine keeps running,,then you need it.

Sorry I couldn't give you a definite answer.

Re: CS 130 help...

Yea... kind of figured

I was looking at the MSD directions and really can't figure out if I'll still need it or not.

Anyway. The CS 130 I bought was for the 89 Pontiac Safari wagon with the 5.0 and AC . Had the correct pulley,metal fan (like stock),4 pin (only need 2).

Now got to finish up the wires at the old external regulator,put the tranny back in and wait for a nice day to "test".

Well, Thanks for the help A few sparks...no fires...well see how it goes.

You bring up a good point Paul. Some of the CS style internal regulators have an internal resistor to keep the 'S' terminal supplied with voltage when the 'S' wire is not connected to a remote sensing point. I believe only a few CS internal regulators work that way though. Seems like it was the heavier duty models like those found on trucks (at one time in history at least). The 'L' (or as the spec sheet above eludes to - the 'I' wire) must be hooked up to excite the alternator. It acts like field power where the 'S' wire is actually sensing the load voltage (though it may have an internal shunt as you indicated). Connecting the 'L' wire to the GEN lamp wire would be a good idea IMHO since it gives you a functional GEN lamp.

Re: CS 130 help...

Ya...that would make sense...the application for the one that I got was 90-93 1 ton pickup with a 454. I got that one because it was clocked the way I wanted.

<scratching head again>...I think I ran a resister inline on that wire as I don't have a GEN light hooked up...I think that has something to do with the Tach that is in there instead of the fuel gauge.
