Charging System: Description

The charging system includes a battery, an alternator with a built-in regulator, and the charging indicator light and wire.

The alternator has six built-in diodes (three positive and three negative), each rectifying AC current to DC current.

Therefore, DC current appears at alternator "B" terminal.

In addition, the charging voltage of the alternator is regulated by the battery voltage detection system. The main components of the alternator are the rotor (A), stator (B), rectifier (C), brushes (D), bearings (E) V-ribbed belt pulley (F). The brush holder contains a built-in electronic voltage regulator (G).
