Section 06 ELECTRICAL SYSTEM
Subsection 02 (CHARGING SYSTEM)
GENERAL
The purpose of the charging system is to keep the
battery at a full state of charge.
Magneto
The magneto is the primary source of electrical
energy. It transforms magnetic field into electric
current (AC).
The magneto has a 3 phase-delta wound stator on
18 poles. Capacity is 380 watts.

Rectifier/Regulator
The rectifier receives AC current from the magne-
to and transforms it into direct current (DC).
The regulator, included in the same unit, limits
voltage at a maximum level (14.5 to 14.8 volts) to
prevent any damage to electrical components.

Battery
The battery is the DC source for the electric
starter, the MPEM, ECM and all accessories.
Fuse
If the battery is regularly discharged, check charg-
ing system fuse condition.

1. MPEM
2. Charging system: Fuse connected to the RED/PURPLE wire
The rectifier/regulator could be the culprit of a
blown fuse.
To check, simply disconnect the
rectifier/regulator from the circuit.
If the fuse still burns, check for a defective wire.
CAUTION:
Do not use a higher rated fuse as
this cause severe damage.
TESTING PROCEDURE
First ensure that battery is in good condition prior
to performing the following tests.
For best results, use the multimeter Fluke 111
(P/N 529 035 868).
