Check continuity between main wiring terminals in the following way:
Item （wire color）
Judgment
Battery (red) and ground
of vehicle block
It is battery voltage.
Ground wire (black) and
ground of vehicle block
There is a lead wire.
Charging coil (white) and
ground of vehicle block
No power flowing
between magneto coil
and ground
Between charging coils
(while 1 and white 2)
There is resistance
between coils
1.5.2 Voltage-current regulator inspection
When main wiring terminal is normal, check if plug of voltage-current regulator is of poor contact and measure
impedance value between terminals of
voltage-current regulator itself.
* Attention
• Do not touch the metal part of multimeter
probe with your finger.
• Check with a multimeter. If impedance
values measured by different multimeters
are not the same, it perhaps the inspection is
not correct.
When impedance value between terminals is
abnormal, replace voltage regulator.
1.6 Magneto Charging Coil
* Attention
Inspection of magneto charging coil can be performed on the engine.
Inspection
Disconnect the 6P connector on the magneto.
Use a multimeter to measure impedance value between white coil of magneto and vehicle block.
Standard value: 0.5-10Ω（20）
If measured value exceeds the standard, the magneto coiling shall be replaced.
