Hayden makes one but it uses quick connects. Some years back Flexalite made a unit with quick connects and had all sorts of issues with the connections, mostly due to crimping issues on the uses part. If you can crimp well it might be useful.

There some SPAL units floating around out there:

I have used the SPAL and it works well if used exactly in the right way. They don't make it anymore as I understand it though. There were issues.

And then there is "delta control" from Delta Control

Never used one so I don't know.

Two big things though, mount the controller well away form heat, like under the fender. Don't put it on the fan shroud or in the open engine compartment. They don't like heat.

Second thing, use a sensor that senses the cooling fluid temperature. It just works way better than probes attached to radiators.

Here is a good read...

I've had a few GM trucks with the CS alternators stock and both went over 250,000 miles with no alternator issues before I sold them. The one in my car is out of a 1991. Are there certain years that are better?

I ordered a smaller crank pulley, should be here next week. According to my math it will slow everything down to the same speed as a stock 91 truck would see a idle and will limit my alternator rpm to below 18,000 at WOT. Hopefully that will solve my problem.

Awesome, thanks guys. I'll look into those controllers.

I'll try the pulley first and then get the alternator tested if I'm still having problems.
I don't believe that just 1000 RPM is causing these problems. There is no mention of RPM limitations on the link I posted earlier that sells these higher quality CS-130's.

There are alternatives to the CS-130 and better quality units at the link I posted earlier.

I've read on some other forums and guys have had the same issues with the stock CS130 and high RPM. Crank pulley is ordered and will be here after the long weekend. I'll try the pulley first and see what happens. The better alternators might not have the same problem, but I'll try one thing at a time. I checked the math on my old V-belt setup and it was turning everything quite a bit slower.

Yes the stock ones had quite a few problems with reliability and I'm sure this RPM related problem is one of them which is most likely related to heat issues which the CS-130 is famous for. All of these problems are addressed with the higher quality versions at the link I posted from Quick Start. http://alternatorparts.com/cs130-alternator.html

The larger pulley is really just going to mask the original problem of reliability and heat issues with the factory original versions.

Links to a lot of good videos on that site. Good post, thanks.

Re: CS130 Alternator issues and Windstar fans.

Timely post, I'm losing voltage myself at over ~5500. Voltage dropping to ~11.9 and then comes back to 13.8 once the rpms dip back to 3500 rpm. I just replaced the alternator to see what happens.

I was looking into something like this that Corvettes run. They either partially or totally disengage at some predetermined - maybe somebody can explain.

Re: CS130 Alternator issues and Windstar fans.

I ordered a pulley set from BBK, should be here in a few weeks. The March pulley I tried last week didn't fit. It was about 9/16" too deep to line up with my other pulleys. I did some more testing, I definitely think the charging issues are Rpm related. It starts cutting out at exactly 4500 and cuts back in when rpm drops below 4500. Tried a known good spare alternator and it did exactly the same thing. So hopefully the under drive pulleys will cure the problem.

Looked into the fan controllers as well. The only one I can get locally is one from Painless Wiring. $360 Cdn for the kit. This one starts the fans at %50 and then goes to 100%. Problem is they don't sell the controller separate, only the complete kit that I already have most of. This might be something I just live with until I can head to the U.S. To buy a controller.

I looked at those pulleys too, from what I see, it looks like they just freewheel on deceleration to reduce load. I don't think they limit the alternator rpm in any way.
