Car Alternator Wiring Diagram. Figure 1 below is a block diagram or a functional diagram of an alternator and its connections to the remainder of the automobile electrical system. The alternator has a rotor that spins when the engine cranks.
The three-phase alternator has two parts stator and rotor. The Number 1 wire on the 10- or 12-SI is connected to the charge warning light on the dash. You can also use 12V on rotor but motor will bi slow and spent 3 amps on rotor.
The alternator has a rotor that spins when the engine cranks.
The headlights dashboard lights radio and interior lights all rely on the alternator to keep the battery charged and the car operating. The stator contains the three-phase armature winding and the rotor contains field winding. And that is all. An alternator works with the battery to supply electricity to components of a vehicle.
