Upgrade to CS style alternator

[Longroof79]

I know this is an old post but after having the same issues with the EC82 connector for myself and a customer, I belive this will finally be resolved. It took a couple calls to Echlin but the called me back today to say they had the connectors mixed together in a batch. Any Napa that orders from Echlin's Viginia warehouse should now recieve the correct connector with resistor. Hope this helps.

Thanks James.
Looks like I'm going to need one with the resistor built in. So the EC82 is the correct one.

Ya Jack the EC82 is the one with the resistor but be sure to visually check for it. It seems there are a lot of incorrectly boxed ones out there. Most Napa's will get them from whatever closest DC has them but they may still be the wrong ones. If it is a problem with your local store you can try to get them to order directly from Echlin.

Thanks James,
I'll give it a shot. My generator light circuit is bad. I took the cluster apart yesterday figuring it was a bad bulb. I tested the bulb and it was good...changed bulbs for the heck of it...still no light. Oddly enough, before I even did all this, the alternator was charging... now it's not. Sometimes I have to learn to leave things alone. :|

Can somebody tell me what ohm resistor I can use? Perhaps if I find one locally, I can add it to the energize wire and save the cost of the adapter. Just another thought.

Jack, were you able to get that worked out?

Steve,
I ended up running a new 16-18ga wire from the fusebox (switched +12 volt) terminal to the charge wire on the alternator. I added a resistor inline. I took a chance and used a 68 ohm 1/2 watt resistor. Painless uses an 82 ohm 5 watt resistor for their si to CS adapter, so I thought it was worth a shot.
It now gets 14.26- 14.30 volts. I forgot how many ohms there was indicated. I think it was in the .456 range..

I was going to order the EC 82 from NAPA, but I thought I'd give this a try.

I think your good with what you did cause I've read that the minimum resistor required is 50.

Thanks Steve,
I was going to go with a 100 ohm resistor since Radio Shack didn't have the 82 ohm in stock. I figured 68 ohm was within a happy medium.
I was concerned about cooking the alternator. After noticing that it wasn't charging, I connected a jumper wire from the oil pressure sender wire to the generator, and that worked fine. Figuring it would simulate the generator warning light circuit.

can anyone tell me if this upgrade will work on a stock buick built 3.8L V6 in an 84 cutlass brougham ? i have the cs144 alt. already just don't wanna screw anything up...lol

Where would I hook this jumper lead to try on a CD alternator?

Note: charged with ec80 harness. Then it quit. Took it to the store and it passes as good. Ordered the ec82 harness made sure i t was correct. Reinstalled alternator with new harness and still doesn't charge. What's the deal?

Sounds like the alternator isn't getting excited.
