Dirt bike Ignition Coil is damaged by breakdown, causing the engine to not start and run normally. Let's take a closer look at what impact it will cause.

The breakdown of the dirt bike Ignition Coil will cause a partial short circuit in the secondary winding, causing the engine to be powerless or even unable to start. The main reasons for its breakdown are the reduction of the dielectric strength of the high-voltage insulation of the secondary winding and the excessively high working voltage. Among them, the decrease in the dielectric strength of the high-voltage insulation of the secondary winding is mostly caused by the damping of the secondary winding, the overheating of the dirt bike Ignition Coil, and the aging of the insulating material. The working voltage of the dirty bike Ignition Coil is too high, which is generally caused by the excessive gap between the spark plug electrodes and the high voltage of the generator. In addition, when the high-voltage line is disconnected, the generated high-voltage electricity has no way to pass, which will also cause the dirt bike Ignition Coil to be broken down.
For example, a car is easier to start when the car is cold. When the engine water temperature reaches the normal water temperature, the running stability gradually decreases, and there is a sound of collision between the starter pinion and the engine flywheel gear ring. When the ambient temperature around the engine increases, the engine begins to shake violently and even stops, and it is difficult to start again.
According to the above phenomenon, the diode and the secondary coil in the dirty bike Ignition Coil assembly were found to be broken down by using the new and old dirt bike Ignition Coil for high-low temperature and high-voltage fire comparison test. Analysis of the failure phenomenon: because the dirt bike Ignition Coil and diode breakdown are not very obvious when the bike is cold, it can still work. When the engine reaches the normal working temperature, the temperature of the dirt bike Ignition Coil increases due to the increase of the ambient temperature, which reduces the insulation level, the secondary breakdown short circuit occurs, the ignition voltage decreases, the spark plug is out of fire, and the engine stops running; The diodes in this dirt bike Ignition Coil assembly prevent the current flowing into the additional resistor from flowing back to the starter solenoid switch.
