Signs of a broken ignition coil
With the weakening of the spark plug's ability to flash, the combustion of the engine's combustible mixture will be affected, resulting in increased fuel consumption and reduced power. The weakening of the spark plug's flashover ability will cause incomplete combustion of the combustible mixture, and the incomplete combustion of the combustible mixture will produce a coke substance called carbon deposition.

What are the precautions for ignition coil maintenance

1. When the engine starts and works, do not touch the high-voltage wire of ignition coil with your hands to avoid electric shock.
2. When checking the circuit fault of the ignition coil, do not use the method of scraping fire to check the continuity of the circuit, otherwise the electronic components will be easily damaged.
3. During the maintenance process of the ignition coil, if it is found to be damaged, or there is a short circuit, open circuit, grounding and other faults inside, the ignition coil of the heart should be replaced in time. 4. Wear insulating gloves and take protective measures during the maintenance of the ignition coil.
5. Non-professionals or those who do not know how to repair cars are not recommended to repair the ignition coil by themselves, so as to avoid more serious failures or safety accidents.

How often should the ignition coil be replaced?

Ignition coil is generally replaced every 100,000 kilometers; the usual ignition coil contains two sets of coils, primary coil and secondary coil; There, the number of their first loops is greater than the number of their sub-loops; when the primary coil is connected to the power supply, the iron core stores its magnetic field in a strong magnetic field around the current growth.
