| Description |
The charging system includes a battery, an alternator with a built-in regulator, and the charging indicator light and wire.
The Alternator has built-in diodes, each rectifying AC current to DC current.
DC current appears at alternator "B" terminal.
The charging voltage of this alternator is regulated by the ECM.
The main components of the alternator are the rotor, stator,
rectifier, capacitor brushes, bearings and V-ribbed belt pulley. The
brush holder contains a built-in electronic voltage regulator.

Alternator Management System
Alternator management system controls the charging voltage
set point in order to improve fuel economy, manage alternator load under
various operating conditions, keep the battery charged, and protect the
battery from over-charging. Battery sensor is mounted on battery (-)
terminal. It transmits battery voltage, current, temperature information
to ECM. ECM controls generating voltage by duty cycle based on the
signals from battery sensor and vehicle operating conditions.
The system conducts discharging control when accelerating a
vehicle. Vehicle reduces an alternator loadand consumes an electric
power form a battery. The system conducts charging control when
decelerating a vehicle. Vehicle increases an alternator load and charges
a battery.
