CHARGING SYSTEM

GENERAL
Magneto
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.
717 Engines
The magneto has a three-pole coil. Capacity is 160
watts.
787 RFI and 947 DI Engines
The magneto has a 3 phase, delta wound stator
on 18 poles. Capacity is 270 watts.
4-TEC Engines
The magneto has a 3 phase, delta wound stator
on 18 poles. Capacity is 380 watts.
Rectifier/Regulator
All Models
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.
717 Engines
A half-wave rectifier receives magneto current
and transforms it into regulated current to allow
battery charging.
787 RFI and 947 DI Engines
The unit is using a 3 phase in series rectifier/regulator
which transforms (AC) from the magneto into (DC) to
allow battery charging.
Battery
The battery is the DC source for the electric start-
er, the Multi-Purpose Electronic Module and all ac-
cessories.
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.
GTI LE RFI Models
The main electric system fuse is 20 A and located
on the cut off relay. Also another 20 A fuse is mount-
ed on the MPEM bracket to protect the rectifier/reg-
ulator.
DI Models
The charging system is protected by 2 fuses.
A 25 A fuse is mounted on the MPEM and a 30 A
fuse is located in the rear electrical box on the cut-
off relay.
4-TEC Engines
The charging system is protected by 1 fuse (30 A).
All Other Models
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.
