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. .
