Where is the problem if a motorcycle has no high voltage electricity?

[LaAddyson]

For an EFI motorcycle without high voltage electricity, the main causes include spark plug, ignition coil, ECU, ignition switch, kill switch or side stand kill switch, damage to sensors related to the ignition system, or open circuits, short circuits, and loose connections in the wiring between these components. Classification of EFI motorcycles: 1. Closed-loop type: The function and role of closed-loop EFI motorcycles are basically the same as those of cars. Closed-loop EFI motorcycles can adjust the fuel injection volume of the injector based on the oxygen content in the muffler, and can also change the intake pressure according to changes in external atmospheric pressure. Most domestic motorcycles seen on the market are open-loop EFI motorcycles. 2. Open-loop type: Open-loop EFI motorcycles have been largely phased out due to their inability to meet high environmental standards.

A few days ago, my motorcycle wouldn't start—there was no high-voltage spark. This issue usually stems from the ignition system. If it won't even light a cigarette, the battery might be dead, so check if it's fully charged. A faulty ignition coil can be diagnosed by testing its resistance. Or, the high-tension wire might be broken, connections loose, or wiring short-circuited due to aging. Dirty spark plugs can also cause no spark—unscrew them to check for carbon buildup. Another possibility is a faulty CDI unit; if this little box is broken, it won't generate high voltage. Remember, don’t slack on regular maintenance—periodically inspect cables and components to avoid roadside breakdowns. After riding motorcycles for over a decade, I’ve encountered this issue often. Sometimes, simply replacing the coil fixes it, saving both time and money.

My motorcycle occasionally loses high-voltage power, which is really annoying. Most of the time, it's due to worn or short-circuited high-voltage wires. Old wire insulation cracks, exposing copper strands, and rusty or loose connections can interrupt the current. Faulty ignition coils are also common—if the coil burns out, there's no output. Also, check the CDI module, which controls high-voltage generation. If it's broken, you'll need a new one. Low battery voltage might also be a factor, so try charging it first. I recommend getting a multimeter to easily check for current flow instead of just guessing. Make it a habit to press the electric start before each ride and listen for any unusual sounds—early detection means early repairs. Experience tells me that regular maintenance of these small components can prevent major headaches.

If the motorcycle has no high-voltage electricity, it's mostly an issue with the ignition system. For example, a problem with the spark plug—if it's dirty or cracked and not sparking, just replace it with a new one. Or the high-voltage wire might be disconnected or loose, causing a power cut. Sometimes the CDI is faulty, leading to unstable output. Try opening the cover yourself to check the connections—don’t be afraid. I often fix things at home, saving money on shop visits. With the right tools, it's easy to handle and a great way to learn. Keeping the cables well-maintained reduces the chances of faults.
