What are the symptoms of a faulty car ignition coil?
1 Answers
The symptoms of a faulty car ignition coil include: 1. Short circuit in the ignition coil winding, which results in too low voltage generated by the ignition coil, causing insufficient ignition energy and faster blackening of the spark plug electrodes; 2. Open circuit or grounding of the ignition coil, leading to no high voltage generation and failure to ignite; 3. Surface discharge of the ignition coil, where discharge sparks appear on the outer surface of the ignition coil; 4. The gasoline-air mixture in the cylinder fails to ignite and is expelled through the exhaust pipe. The causes of a faulty car ignition coil are: 1. Excessive gap between the spark plug electrodes; 2. Engine overheating; 3. Open circuit in the high-voltage wire; 4. Heat effect generated by current; 5. Poor quality gasoline; 6. Incorrect cylinder compression ratio; 7. Program failure in the computer board.
