Anyone wired this up yet?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am in the process of installing a new (new to me, anyway) V-8 in my truck. I am using a serpentine setup, with an internally regulated alt. I have read all the posts I can find on bypassing the external regulator and that all makes sense. BUT....in every post I can find, it tells you that you have to leave the wires connected that go to the idiot light in order for it to work properly.

I am going to be using all aftermarket gauges (AutoMeter Pro-Comp series) in my dash and doing away with the idiot light stuff.

So how do you wire up the internally regulated alt. to work with no idiot light and no factory gauge?

Surely someone has done this. Any information you can offer will be GREATLY APPRECIATED. (pics would be nice, also.)

You can order this wiring kit http://www.madelectrical.com/catalog/cs-130.shtml and you should read up on how it works here... http://www.madelectrical.com/electri...esensing.shtml

Anyone else? I read the links above, and it seems helpful, but can it be done without a store-bought kit?

I assume you have a CS style alt? If so all you need is a resistor (35-75ohms 3watt)between an ignition switched source and the L terminal on the alt plug. This is the exciter wire. Do not put straight 12V to this it will burn out the exciter circuit in the alt. The S terminal is the voltage sensing wire. Those are the only hook-ups you need to the plug leave the other two terminals blank.

If it a 2 wire one hers what you can do. Go to the junk yard and get the plug that goes in to the alt with some wire left. The heavy wire is your main charge wire and it ties into the heavy read wire that runs across the top of the rad. The other wire is your excite wire you conect it to a small bulb( I used a marker light) and tie it into a ignition hot wire under the dash. When the key is turned to the on position the exciter wire is grounded and the light will turn on. When the truck starts the exciter wire bcomes positive and the light will go out. Tryed to make it very simple hope it helps.
