First, after removing the spark plug, gently step on the starting rod with your foot, and the rotation is too easy to feel that there is no magnetic absorption of the coil core, which is the performance of magneto magnetic decline.

Second, in the shutdown, open the magneto side cover, with a small driver close to the flywheel inside the magnetic steel top, poor suction is the performance of magnetic decline.

Third, when the magnetism of the magnet on the flywheel decreases to a certain point, it can not give enough ignition power, and the spark plug is difficult to jump the fire motorcycle is difficult to start.

Fourth, the general motorcycle in the headlight switch with the foot to quickly step on the starting rod, the headlights should have a slightly bright performance, if not bright, indicating that the power generation capacity is limited. However, this trick is only suitable for AC headlights.

Fifth, in the magneto lighting power line output connected to the AC voltmeter, you can know the power generation capacity: the load voltage when the headlight and the no-load voltage when the headlight is too different, is the performance of insufficient power generation capacity, that is the virtual voltage.

Six. When the engine is running at full speed and the headlight is at its brightest, the voltage X current at the output end of the lighting power line = the maximum output power wattage of the magneto (IXV = W)
