I thought I read on another link that I needed to put a 'resistor' on the alternator when coverting to a cs144? Is this true? If so, is it the brown wire and how much resistance is needed? The guy at the alternator shop told me today that I dont need one.

Do you have an idiot-light or a gauge on your dash? You don't need a resistor if you have a light, although you could wire one in to protect your alternator in case the light burns out.

when i spliced the new connector into my harness (lectric limited) to fit the cs type alternator, i noticed that one of the wires was not copper, but a stiff silver color. i believe that it is a resistance wire needed to create the voltage drop to make the alternator excite properly.

OK, so Brown wire to the "L" connector on the alternator plug and also, putting a 33 ohm resistor on this same wire since I have the voltage gauge. May work on it later today, so thanks for the help all.

Just because you have a gauge doesn't mean that you don't have a light. Is there a "GEN" light in your center cluster?

OK, didn't think about that. I looked and it looks like it has been disconnected. I installed an aftermarket voltmeter a long time ago. Would having a resistor AND the idiot light be a problem?

I kind of like having the light there - instant "heads up" notice that something is acting up.
