CHARGING SYSTEM 0
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 (AC).
The magneto has a 3 phase, “Y” wound stator on
18 poles. Capacity is 180 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 components.
A dual 1/2 wave series rectifier receives the mag-
neto AC current and transforms it into direct cur-
rent (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.
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.
TESTING PROCEDURE
NOTE: First, ensure that battery is in good condi-
tion prior to performing the following tests.
Rectifier/Regulator
NOTE: On the 947 engine, the rectifier/regulator is
integrated in the MPEM.
STATIC TEST: CONTINUITY
Due to internal circuitry, there is no static test avail-
able.
DYNAMIC TEST
Current Test
Proceed as follows:
– Start engine.
– Lay an inductive ammeter on positive cable of
battery.
– Bring engine to approximately 5500 RPM.
Depending on battery charge, current reading
should be approximately 5 amperes for the 947
engine. If not, check magneto output prior to con-
cluding that rectifier is faulty.
Voltage Test
Proceed as follows:
– Start engine.
– Connect a multimeter to battery posts. Set mul-
timeter to Vdc scale.
– Bring engine to approximately 5500 RPM.
If multimeter reads over 15 volts, regulator is de-
fective. Replace it.
NOTE: If it is continually necessary to add distilled
water to the battery, this indicates an over voltage
situation, requiring replacement of the rectifier/
regulator. If, on the other hand, the battery will not
stay charged, the problem can be any of the charg-
ing circuit components. If these all check good,
you would be accurate in assuming the problem
to be in the rectifier/regulator.
