a 3 wire alt has 1-12 ga. wire that's hot all of the time (from the bat.) that goes to the post on the back of the alt. in the plug you have 2 wires 1 about 14 ga. and one that's about 18 ga. (the little one) the big one in the plug is hot all of the time 12 volts and the little one is hot when you turn the key on, the little one excites the voltage reg. to get it going. To make your alt a 1 wire alt. do away with the plug, you don't need that anymore. then come off of the 12 volt post at the back of your alt and run yourself a short 12 ga. wire from the post to where the big wire was in the plug. thats all you have to do. when you crank the motor some times you have to idle it up some to get the alt to charge, but ive done that for yrs without a problem. if you don't under stand this let me know and ill get you a diagram. #1-12 volts 12 ga. wire to the big post on back of alt.#2- run a 12ga. wire from the post on the back of the alt to the right hand spade in the top of the alt. or the spade where the big wire came from in the plug in the top of the alt. don't take but a min.
