The purpose of the charging system is to keep the
battery at a full state of charge.
The magneto is the primary source of electrical
energy. It transforms magnetic field into electric
current.
The magneto has a three-pole coil.
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 components.
A half-wave rectifier receives magneto current and
transforms it into regulated current to allow bat-
tery charging.
Battery
The battery is the DC source for the electric
starter, the Multi-Purpose Electronic Module and
all accessories.
Fuse
If the battery is regularly discharged, check fuse
condition.
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.
Two 15 A fuses protect the charging system. The
first one is mounted on the MPEM and the other
one is located in the rear electrical box on the cut-
off relay.
