Spark Plug Ignition
1. Remove the spark plug cap from the spark plug.
1. Spark plug cap; 2. Spark plug
2. Connect the ignition detector to the spark plug cap.
3. Start the engine and observe the spark through the discharge window of the detector.
Warning:
Do not touch any joint of the detector lead.
Stay away from combustible gases or liquids to avoid accidents caused by spark ignition.
Spark Plug Cap
1. Unscrew spark plug cap. Check the spark plug cap for damage. Replace it if necessary.
2. Install spark plug cap.
Flywheel Maintenance
1. Remove the flywheel nut using the flywheel gripper; Remove the flywheel using the
flywheel puller.
2. Check whether the flywheel is damaged and whether the permanent magnet is firm.
Replace it if necessary.
Check the Ignition Coil
1. Remove the ignition coil and the spark plug cap.
2. Measure the resistance of the ignition coil. If the specified value is not met, replace it.
Primary resistance: 2.2±0.22Ω
Secondary resistance 9.84±0.98kΩ
Check the trigger coil
1. Trigger coil peak voltage
Use a digital multimeter and a peak voltage adapter to measure the coil output peak
voltage. If it is below the specified value, check the tri|gger coil resistance.
Digital multimeter Peak voltage adapter
Pulse coil peak voltage: ≥13 V@1000 r/min (load)
