1. There is no spark in the high voltage package and the vehicle cannot start.
2. Once the high voltage package loses electricity, the vehicle will feel frustrated while driving, sometimes going faster and sometimes slower. If the leak is significant, cyclists in the vehicle will feel like they are being electrocuted.
3. Once the breakdown current of the high voltage assembly becomes low, it will cause insufficient combustion, vehicle weakness and increased fuel consumption.
The main function of the motorcycle high voltage assembly is to generate high voltage electricity to ignite the combustible gas mixture in the cylinder through the spark plug. To put it simply, it is a miniature transformer that converts low voltage to high voltage. When the motor is running at high speed, its voltage can reach around 20,000 volts.
The motorcycle's high voltage assembly is a step-up transformer that increases the 6V or 12V voltage generated by the motorcycle's generator to 12,000V and sends it to the spark plug to 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, simply remove the spark plug, connect it to the spark plug sleeve and twist it. on the ignition key.
Press the outer end of the spark plug against the engine, press the motorcycle start lever with your foot and watch the spark plug fire. The sparks are blue and the crackling sound is clear and powerful. , indicating that the high voltage box is intact and there is no spark. This means that the high voltage box has been burned and the sparks produced are dark red, indicating that the coil inside the bHigh voltage box is short-circuited. and should be discarded.
The working principle of the high voltage box is to convert direct current to alternating current through an oscillator, increase the voltage through a step-up circuit, and rectify it to high voltage direct current when the voltage reaches a certain value. , it powers the igniter.
Detailed information:
1. The principles of starting motorcycles and cars are similar. The simplest starting conditions are: oil supply and high pressure. fire.
2. When the oil circuit is normal, if the high pressure assembly is damaged, it will naturally be unable to provide high pressure power for ignition of the spark plugs.
3. If it is not completeIf the engine is damaged, such as poor conduction or leakage, it will also cause abnormal ignition, intermittent or stopped ignition, resulting in poor acceleration, poor starting or poor driving. statuses such as extinction.
When some malfunction 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 just need to do this. Check the high voltage assembly and ignition circuit, spark plugs and other related parts or parts.

No, spark plug problems and ignition circuit problems will cause this.
1. Spark plug problem: The spark plug may have high pressure and misfire for reasons such as excessive life or dirt.
2. Ignition line problem: Ignition line failure or poor contact will cause high voltage failure and the line must be inspected and repaired.
