Why does the car keep burning out ignition coils?
1 Answers
The main reasons for ignition coil burnout are insulation layer aging breakdown or switching transistor damage. The reasons why ignition coils frequently burn out are as follows: 1. Generator issue - if the power generation is too high, the ignition coil may overload and burn out. 2. Excessive spark plug gap - adjust the gap or replace the spark plug. 3. Poor gasoline quality - switch to higher octane gasoline. 4. Incorrect cylinder compression ratio - adjust the compression ratio. 5. ECU program failure - have the vehicle scanned at a repair shop to clear error messages. 6. Unstable power supply voltage. 7. Excessive primary current from the ignition controller causing ignition coil overheating.
