1. After removing the spark plug, lightly press the starter lever with your foot. If it spins too easily and there is no feeling of magnetic attraction on the coil core, this is a sign that the magnetism of the magneto has diminished.
2. When the machine is stopped, open the side cover of the magneto and use a small screwdriver to get closer to the magnet inside the flywheel. Poor suction is a sign of. loss of magnetism.
3. When the magnetism of the magnet on the flywheel decreases to a certain extent, it will not be able to provide enough ignition power and the spark plug will The ignition will be difficult to spark, making it difficult to start the motorcycle.
4. For ordinary motorcycles, when you turn on the headlight switch and quickly press the start lever, the headlights should light up slightly if they do not turn on. do not light up. meante that power is generated. Capacity is limited. However, this tip is only suitable for AC headlights.
5. Connect an AC voltmeter to the output end of the magneto lighting power line to find out the power generation capacity: the difference between the voltage of charge when the headlights are on and the no-load voltage when the headlights are off. If the gap is too large, it is a sign of insufficient energy production capacity, which is virtual voltage.
6. When the engine is running at full throttle and the headlights are at maximum, the voltage maximum output power magneto power (IXV=W)< /p>
