Common faults of automobile high-voltage circuits

The high-voltage line falls off or leaks; the distributor cover is broken and broken; the distributor burner is ablated, broken and broken; the spark plug electrode gap is too large or too small; the spark plug has too much carbon deposition; the spark plug insulator is damaged; the ignition coil is damaged or the wiring is off. High-voltage circuit faults mostly use the high-voltage fire test method, that is, unplug the high-voltage line in the center of the distributor or a high-voltage line in a certain cylinder, place the wire head at a distance of 3-6mm from the cylinder body, and start the engine to test the fire. There are sparks and the sparks are strong, indicating that the ignition system is working normally. .
