When a motorcycle is driven for a long time, various problems will inevitably arise. Among them, the high voltage package that does not light up is a very troublesome problem for the owner. There are three common reasons why a motorcycle's high voltage assembly will not turn on:
1. The low voltage ignition coil is burnt out. The ignition generally consists of an ignition coil and a spark plug. When the low-voltage ignition coil burns, it cannot supply high voltage to the spark plug to release sparks, and misfire will occur.
2. The output power cord plug is loose. If the igniter's power cord plug is loose, it will not be able to provide the current needed for ignition due to poor contact with the wire.
3. The extinguishing switch is defective. Failure of the extinguishing switch will result in the inability toe transmit the ignition information and the ignition system will naturally not ignite if it is not working.
The high voltage box is a line output transformer, also called a line box or line transformer. Its main function is to generate high anode voltage and also provide focusing, accelerating, gate and other voltages. The motorcycle's high-voltage package 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.
Since the high voltage box operates at high temperature, high frequency, high voltage and high current, coupled with the influence of factors such as humidity or dust in the external environment, the probability of damage to the high voltage package is high. To check the quality of the high voltage assembly, simply remove the spark plugand connect it to the spark plug sleeve, turn on the ignition key, press the outer end of the spark plug against the engine, press the motorcycle start lever with your foot and observe the ignition of the candle.
If the sparks are blue and the crackling sound is clear and loud, the high voltage box is intact. If there are no sparks, the high voltage box has been burned. the sparks are dark red, this means the coil inside the high voltage box is short circuited. Today's high voltage enclosures are all sealed. If they break, they can only be replaced with new ones.
