Main reasons:
1. Check the spark plug. Do not use it for too long and the gap should not be too big. Replace it with a new one if necessary.
< p>2. High voltage wires must meet standards. High voltage and high temperature resistant wires and contact with the ignition coil plug must be properly matched.3. there is no breakdown or current leakage.
The working principle of the ignition coil:
The reason why the ignition coil can convert The low voltage electricity of the car in high voltage is that it has the same shape as an ordinary transformer, and the transformation ratio between the primary coil and the secondary coil is large. However, the working mode of the ignition coil is different from ordinary transformers. Ordinary transformers operate continuously, while ignition coils operate continuously.sound intermittently. They store and discharge energy repeatedly at different frequencies based on different engine speeds.
When the primary coil is turned on, a strong magnetic field is generated around it as the current increases, and the iron core stores the magnetic field energy; when the switching device disconnects the primary coil circuit, the magnetic field; of the primary coil In rapid decay, a very high voltage will be induced in the secondary coil. The faster the magnetic field of the primary coil disappears, the higher the current when the current is disconnected, and the higher the turns ratio of the two coils, the higher the voltage induced by the secondary coil.
Hello, your problem occurs after the car has been driven for a while, correct? It should be a minor fault in part of the circuit. We estimatethat the ignition coil is connected to the igniter. It is recommended to replace the DC igniter, because after replacing the DC igniter, the battery is used for ignition, so there is no need to replace the coil. You get two benefits with one, but there is a downside. The counter will not move. Fix the problem; Speedometer There are three wires, a positive, a negative and a sense wire. Replace the sense wire with the black and yellow wire from the large wire package. I've been a repairman for seven years,,,, haha, I'm laughing at the problem. . I hope this helps you.
I hope this is helpful and I hope you adopt it.
