What are the reasons for the Honda CBR23 having no high voltage?

Honda CBR23 having no high voltage may be due to a damaged high voltage coil. Introduction to the high voltage coil: Its formal name is the line output transformer, also known as the line coil or line transformer. Its main function is to generate anode high voltage and also provide various voltages such as focus, acceleration, and grid. Since the high voltage coil operates under conditions of high temperature, high frequency, high voltage, and large current, combined with external factors like humidity or dust, the probability of high voltage coil damage is relatively high. Reasons for high voltage coil damage: Breakdown of the internal high voltage filter capacitor; inter-turn short circuit of the internal high voltage coil; leakage or breakdown of the internal high voltage silicon stack; short circuit of the internal primary and secondary coils; aging of the internal focus component, causing unstable focus and acceleration voltages; decreased insulation performance of the coil body, leading to internal or external arcing of the high voltage coil.
The Honda CBR23 has no high voltage, an issue I've researched many times. The absence of high voltage is caused by a missing key component in the ignition system. Common causes include ignition coil failure, which may result from internal short circuits or aging; damaged or loose spark plug wires, as poor wire contact prevents electricity transmission; blown fuses are another frequent issue, where high current overloads burn out the fuse; insufficient battery power, rendering ECU-controlled ignition ineffective; and corroded or water-damaged high-voltage wires or plugs, especially prone to rust after riding in the rain. I recommend starting with a battery check to verify voltage, then systematically testing the fuse, ignition coil, and spark plug connections. Regular maintenance should include clearing moisture around the engine and periodic spark plug replacement to prevent this issue. Long-term neglect can lead to difficult engine starts and even compromise riding safety.
