1 wire internal or external oem alternator
Also note: you can make a single wire alternator with an adjustable voltage regulator mounted on the alternator. It senses the engine running and when the car is on high idle starts the charge. It stops when either the voltage demands are met or you shut off the engine. They are pretty good but typically made in Chyna.
