I took my one wire alternator to a local Alternator/Starter motor repair shop and had it converted back to a three wire. Cheap and no problems.

The wiring is still very simple. The large wire goes from the BAT terminal on the alternator and then goes to the BAT terminal on the starter solenoid. This is for either the three wire or one wire hookup. For the three wire; the exciter wire (#1 terminal on the alternator) goes thru either a diode or a charging light (idiot light) and then to the ACC terminal on the ignition switch. The wire from the #2 terminal on the alternator is a short jumper wire that connects to the BAT terminal on the alternator. It is also a good idea to connect a short wire from the ground post of the alternator to the engine block.
