Disconnect the two 6P input connectors
on the inverter unit. (6p for single
voltage , 4p or 2p for double voltage)
Disconnect spark plug cap or igniter
connector, measure the AC voltage of
main winding and sub. Winding when the
stator motor is running. Measure one AC
voltage of main winding or sub. Winding
for double voltage unit.

→abnormal
1. Check the wiring of the stator leads in
the harness. Repair or replace the
harness.
2. Rotor internal magnetic weaken,
replace the rotor.
i. No AC output
Is the engine speed normal?
abnormal
Perform the throttle control system
Measure the resistance between two
blue wire on the rectifier
→abnormal
Check and repair the wire harness or
replace the stator
Rotor losses excitation, replace the rotor
j. Electric starter doesn’t run.
Check the battery voltage
Replace the ignition switch
Replace battery switch( sucking coil)
Replace the starting motor
Check and repair or replace main wire
