Hy Gene_Spartan80, a three wire alternator needs to be turned on by something, either with wiring or by higher R.P.M. than idling, wiring the number one wire (if that is the alternator excitation wire, I can't remember) to the "R" terminal of the starter solenoid will "turn on" the alternator while the engine is being cranked, once "turned on" the alternator will continue to charge until the engine is shut down, hope that clarifies. This procedure only applies to vehicles whose ignition system is of a type that no longer needs or uses the ballast resistor system.
