2.2 Failure Diagnosis

Spark plug fails to jump.
Ignition
Coil
No or interrupted high voltage electricity
Secondary
Side
Voltage
Normal high voltage electricity/no spark for the
Charging
Coil
No or interrupted high tension electricity
Trigger
No or interrupted high voltage electricity
Error
Low Voltage
plug
No high voltage electricity
Low high voltage electricity
Reason（in compliance with the following order）
①
The inner resistance is too small and it should be tested
by required tester.
②
Low rotation speed of the bent axle.
③
Tester is interfered. (It is normal that several measured
voltage is above the basic standard.).
④
Poor contact wire for the ignition system.
⑤
Bad ignition coil.
⑥
Bad charging coils (measure at maximum voltage).
①
Wrong connection with the tester.
②
Bad main switch.
③
Bad connector of the CDI group.
④
Poor contact of the CDI group or GND of the CDI
group is short-circuit.
⑤
Bad charging coil (measure at maximum voltage) .
⑥
Bad trigger（measure at maximum voltage）.
⑦
Bad high tension electricity connector.
⑧
Bad CDI group (when there is no spark for the plug or
①-⑦ is abnormal).
①
Bad plug or secondary ignition coil leakage.
②
Bad ignition coil.
①
The inner resistance is too small and should be tested by
required tester.
②
Low rotation speed of the bent axle.
③
Tester is interfered. (It is normal that several measured
voltage is above the basic standard.).
④
Bad charging coil（①-③ are normal）.
①
Bad ignition coil.
②
Bad charging coil.
①
The inner resistance is too small and should be tested by
required tester.
②
Low rotation speed of the bent axle (It is normal that
several measured voltage is above the basic standard.)
③
Tester is interfered.
④
Bad trigger（①-③ are normal）.
①
Bad ignition coil.
②
Bad trigger
