The Role of Ignition Leads (Ignition Cable) in Automotive

What roles do the ignition cables play when installed in the vehicles? Maax,the top Chinese manufacturer of ignition coils, ignition cables etc shows the answers as below：
 
1. The high-voltage cable (ignition cable) of the automobile is to protect the normal operation of the ignition system and the electrical system of the whole vehicle;

2. The ignition voltage can be increased, when the spark plug deposits too much carbon, it will cause a fire due to leakage, and the ignition voltage can be increased by resistance, which is easier to break through the spark gap and make the spark strength normal;

3. The resistive high-voltage cable plays a role in the current sharing of high-voltage distribution;

4. Extend the discharge time of the spark plug and improve the ignition rate.

Maax's ignition cable expert also give answers of how to judge the ignition cables fail:

If the vehicle's ignition coil breaks, the electrical spark released by the spark plug will take on a dull yellow color, and the energy will not be enough to ignite the fuel mixture well.

The severe energy shortage could not even make the electrodes of the spark plug release an electric spark, causing the fuel mixture not burn, resulting in a shortage of cylinders. A shortage of engine cylinders reduces engine power, increases fuel consumption, and jitter and noise are very noticeable.

If the engine cylinders only inject fuel for a long time without ignition, it can also cause gasoline to overflow. To determine which cylinder's high-pressure coil is damaged, you can use the method of adjusting the high-pressure package of each cylinder. However, some models have a single high-voltage coil, so only all
