Detection of magneto coil
Measure the peak voltage of magneto coil (between green wires).
Use digital multimeter and peak voltage adapter to measure the peak output voltage of
the coil. If it is lower than the specified value, replace the magneto coil.
Detection of rectifier regulator
Measure the peak voltage (DC) of the rectifier regulator.
Open the rectifier output (red wire and black wire) and use a digital multimeter to measure
the voltage between the red wire and black wire at the rectifier regulator output.
If it is lower than the specified value, check the peak output voltage of magneto coil. If the
peak output voltage of magneto coil is higher than the specified value, replace the rectifier
regulator.
Use fault diagnosis tester
When the engine is running, if the fault indicator on the bottom cover is always on/buzzer is
always on, it indicates that there is a fault in the engine. At this time, connect the fault diagnosis
tester with the corresponding detection port on the engine, and display the running parameters and
fault codes of the engine on the mobile phone through the APP. Then check the fault code table to
determine the engine fault and replace the faulty electrical components.
