1. There is no spark in the high-voltage package and the vehicle cannot start.

2. Once the high-voltage package leaks electricity, the vehicle will feel frustrated while driving, sometimes going faster and sometimes slower. If the leakage is severe, the cyclists on the vehicle will feel like they are being electrocuted.

3. Once the breakdown current of the high-voltage package becomes low, it will cause insufficient combustion, vehicle weakness, and increased fuel consumption.

The main function of the motorcycle high-voltage package is to generate high-voltage electricity to ignite the combustible mixed gas in the cylinder through the spark plug. To put it simply, it is a miniature transformer that converts low voltage into high voltage. When the engine rotates at high speed, its voltage can reach about 20,000 volts.

The motorcycle high-voltage package is a step-up transformer, which increases the 6V or 12V voltage generated by the motorcycle generator to 12,000V and sends it to the spark plug for ignition. Today's high-voltage packages are all closed. If they are broken, you can only replace them with new ones. To check the quality of the high-voltage package, just remove the spark plug and connect it to the spark plug sleeve, and turn on the ignition key.

Lean the outer end of the spark plug against the engine, step on the motorcycle starting lever with your foot, and observe the ignition of the spark plug. The sparks are blue and the crackling sound is clear and powerful, indicating that the high-voltage package is intact and there is no spark. It means that the high-voltage package has been burned, and the sparks produced are dark red, indicating that the coil inside the high-voltage package is short-circuited and should be scrapped.

The working principle of the high-voltage package is to convert DC into AC through an oscillator, boost the voltage through a boost circuit and then rectify it into high-voltage DC. When the voltage rises to a certain value, it supplies power to the igniter.

Analysis of the reasons for the failure of the high-voltage package of the trailer:

1. The starting principles of motorcycles and cars are similar. The simplest conditions for starting are : There is oil supply and high-pressure fire is generated.

2. When the oil circuit is normal, if the high-pressure package is damaged, it will naturally be unable to provide high-pressure supply for spark plug ignition.

3. If it is not completely damaged, such as poor conduction or leakage, it will also cause abnormal ignition, intermittent or stopped ignition, resulting in weak acceleration, poor starting, or poor driving. There are various statuses such as flameout.

When some fault phenomena such as the above occur, it can be judged from two aspects, one is the oil circuit, and the other is the ignition circuit. When the oil circuit is normal, you only need to check the high-voltage package and ignition circuit. , spark plugs and other related parts or parts.
