The engine uses a brushless alternator.
Main alternator components are the rotor, the stator, the
rectifier, the front and rear brackets, the IC regulator, the
bearings, and the pulley.
Moving parts include the rotor and the pulley.
The field coil is installed to the rear bracket.
6 main diodes (3 positive and 3 negative) in conjunction
with 2 sub-diodes provide 3-phase rectification. The
diodes are installed to the stator coil.
An additional 3 diodes (diode trio) are used to provide
field current.
The alternator has 3 terminals.
a. Terminal B: DC power output
b. Terminal L: Exciting current input
c. Terminal R: Exciting current input
Terminal R is active only until the alternator begins to
generate electricity.
Terminal L also serves as a voltage output terminal.
When the voltage across terminal L is equal to the
battery voltage, the indicator lamp (no charging) turns
off.
Sealed bearings requiring no lubrication are used
throughout the alternator.
The IC regulator is a solid-state device and is serviced
as a unit. It cannot be disassembled.
