Flywheel Magneto
Connect the hand tester [A] to the connector [B] as shown
in the table 1, using the needle adapter set [C].
Start the engine.
Run it at the rpm given in the table 1.
Note the voltage readings (total 2 measurements).

50 V AC
If the output voltage shows the value in the table, the mag-
neto operates properly.
If the output voltage shows a much lower reading than that
given in the table it indicates that the magneto is defective.
To check the stator coil resistance as follows.
Stop the engine.
Disconnect the auxiliary leads.
Connect the hand tester as shown in the table 2.
Note the readings (total 2 measurement).
Table 2 Stator Coil Resistance
Tester (+) to
× 1 Ω
Red lead
× 10 Ω
Green/White lead
If there is more resistance than shown in the table, or no
hand tester reading (infinity), the stator has an open lead
and must be replaced. Much less than this resistance
means the stator is shorted, and must be replaced.
Using the highest resistance range of the hand tester,
measure the resistance between each leads and chas-
sis ground.
Any hand tester reading less than infinity (∞) indicates a
short, necessitating stator replacement.
If the stator coils have normal resistance, but the voltage
check showed the magneto to be defective; then the fly-
wheel have probably weakened, and the flywheel must
be replaced.
