Why are high-voltage coils prone to failure?

[Ronnie]

High-voltage coils are prone to failure due to the following reasons: 1. Overloading of the ignition coil, where excessive power generation can damage vehicle electrical components, bulbs, etc., leading to the ignition coil burning out and resulting in no high-voltage spark; 2. Abnormal wiring causing short circuits or other malfunctions in other parts or electrical facilities; 3. ECU burnout or wiring damage can also make the vehicle's high-voltage coil more susceptible to damage. The correct name for the high-voltage coil is the line output transformer, also known as the line coil or line transformer. The working principle of the high-voltage coil in displays is essentially the same as that in televisions, with its main function being to generate anode high voltage, in addition to providing voltages for focusing, acceleration, and grid circuits.
