How does a 3 wire alternator charge the battery?

The magnetic field creates a current which feeds through the alternator charge the car’s battery. The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter.
