GENERAL
NOTICE
When performing a test with the en-
gine running above approximately 4500 RPM
for 3 seconds, be aware that suspension will
move up to its predefined position then, it will
stop in that position. Wait until suspension
is stopped before working on the watercraft.
Keep away from moving parts.
SYSTEM DESCRIPTION
The purpose of the charging system is to maintain
the battery at a full state of charge and to provide
the electrical system with the required electrical
power for normal vehicle operation.
Magneto
The magneto is the primary source of electrical
energy. It transforms a magnetic field into an elec-
tric current (AC).
The magneto has a 3 phase, delta wound, 18 pole
stator that is rated at 380 watts.

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

Battery
The battery supplies DC power to the electric
starter for cranking the engine. During engine
starting, it also supplies DC power to every elec-
trical and electronic system in the vehicle as well
as all accessories.
At low engine RPM operation and high current
load conditions, it supplements the magneto
output and helps to maintain a steady system
voltage.
