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 serious, cyclists in the car will feel like they are being electrocuted.
3. Once the breakdown current of the high voltage assembly becomes low, it will cause insufficient combustion, weaken the vehicle and increase 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 wholehe motorcycle high voltage 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 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, 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 high voltage boxnsion 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.

Analysis of the reasons why the trailer high voltage package is broken:
1. The principles of starting motorcycles and cars are similar. . The simplest starting conditions are: There is an oil supply and a 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 completely 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.

The motorcycle cannot produce electricity, there is no fire, the ignition and the pack high voltage are not broken. broken somewhere.
Hot If the car can start without a high voltage electric cooler, the problem is usually causedby the magneto stator coil (including the ignition coil and trigger coil), and sometimes it can also be caused by the igniter. If the newly replaced coil still has this problem, you can check if the igniter is damaged or if there is a problem with the newly replaced coil.
Motorcycles do not have high voltage electricity. In addition to the ignition and high voltage package, the stator magneto coil, power door lock switch and power off switch (it's the big red button on the right). manual handle switch, but this is not the case. All cars have kill switches), and if there is a problem with the wiring between them, there will be no high voltage power. If it is determined that the igniter and high voltage assembly are not damaged, use a multimeter to measure whether the magneto stator coil (including the ignition coil and starter coilignition) is normal, measure whether the ignition system wiring is normal and check whether the ignition shut-off wire (for AC ignition vehicles) is normal. If there is a short, check to see if there is power to the ignition power cord. If it is a car with an electronic induction tachometer, also check if the power cord of. the tachometer is short circuited.
