How to Solve the Problem of Frequently Burning Out Ignition Coils?
2 Answers
First, check the generator issue. If the power generation is too high, the ignition coil may be overloaded and prone to burning out. If there is a program fault in the computer board, you can take the car to a repair shop for a computer diagnosis and clear the error messages. Poor-quality gasoline may also be the cause. Try switching to higher-grade gasoline.
I often encountered the issue of ignition coils repeatedly burning out during car repairs, and the reasons can be quite complex. The most common causes are aging spark plugs or excessive gaps, which can overload the coil, causing it to overheat and burn out. Another frequent issue is poor contact in the high-voltage wiring, leading to short circuits and excessive internal coil temperatures. Additionally, excessive generator output voltage is a common factor—voltages above 14 volts can accelerate coil damage. I recommend starting with simple checks: measure the condition of the spark plugs, and replace them promptly if the gap is abnormal or if there's leakage. Next, inspect the high-voltage wires for cracks or corrosion—replacing them with a set of high-quality cables can help. Ensure the car has good ventilation while driving to prevent engine overheating from affecting the coil's heat dissipation. During regular maintenance, use professional tools to test the voltage of the entire ignition system to prevent issues from escalating. Don't delay, as this could not only cost more money but also lead to stalling on the road, compromising safety.
