I'm interested in running an altenator but I have yet to find out how to hook a stock one up using one or two wires. I have been told it can be done but how? All help would be greatful or maybe a website I can go to.

I believe you can take two small wires from plug and wire together run to key switch take the big wire run to battery

Gm alternators are easy to wire. on the two wire plug there is usually a large red wire and a small brown wire. take the red wire and run it directly to the post on the back of the alternator. then run a large wire from that post to the battery. Thats it.

the brown wire is optional. as long as there is power at the red wire at the plug the alternator will turn itself on. with stock pulleys, say a 6 or 7 inch crank and the factory 2 1/2 inch alternator pulley the alternator will kickon around 1500-1700 RPM. with a 6 inch crank pulley and a 5 inch alt pulley it turns on around 3000 RPM.

If you wire it that way it will run down the battery,i'd run the field wire to a seperate switch and not the ignition switch(car won't turn off)or better yet buy a one wire regulator.

if you are going to run an alternator, wire it like o5racer said to but run the brown wire [or field] to keyed ignition using a small 12 volt light[something with a 194 bulb]wired in series inbetween your ignition and field. now you will be able to shut car off and alt will charge like normal.

by using a ford starter silenoid and putting a jumper on your starter you only have to run the main power wire to the starter thus eliminating the chances of burning starter wires in two while racing i learned the hard way

I read in Circle Track somewhere that the alt takes less than 1 hp to run.

So why not run one?

Run the alt and run the optima.

Cut on rotating accessories elsewhere. Fan, gears in tranny, etc.

Run an e fan.
