How to Solve the Problem of a Scooter Not Starting and Making Noise?

If it is confirmed that the battery has sufficient power and the wiring is in good condition, you can use a pair of pliers or another metal tool to directly connect the two thick wire terminals of the relay. Use the kick starter to press the starting lever. If it can be pressed and the engine can rotate (without starting), it means the engine is not the issue. Check if the battery connections are loose or if the battery terminals are corroded. You can scrape both the battery wires and the terminals.
Last time I also encountered the issue where the scooter wouldn't start and made a clicking sound. It was probably caused by insufficient battery power. As the battery ages with prolonged use, its energy storage capacity decreases, causing the starter motor to fail to turn but still make noise. A simple solution is to charge or replace the battery. Also check the spark plug; a dirty or burnt-out spark plug can cause ignition failure—try cleaning or replacing it. If the fuel tank is empty or the fuel line is clogged, the engine won't get fuel and will make abnormal noises. Check the fuel tank and fill it up, and ensure the fuel line is clear; otherwise, clean the carburetor. For safety, don't force it—if internal parts are damaged, take it to a repair shop as soon as possible. Regular battery maintenance and proper refueling habits can prevent this issue.
During car repairs, it's common to encounter such situations where noises mostly come from starter motor failures or loose battery connections. First, check if the battery terminals are tight and free from corrosion. When the voltage is insufficient, the motor may spin idly and make noise, but it can return to normal after charging. Excessive carbon buildup on spark plugs or loose high-voltage wires can also cause ignition failure, leading to the engine being unresponsive but producing abnormal noises. It's recommended to replace them or re-secure the wire connections. A non-functioning fuel system is another issue; check the fuel tank level and fuel pump operation, and clear the fuel lines if necessary. Regular maintenance, such as cleaning spark plugs and checking the battery, can significantly reduce the risk of such failures.
Failure to start with noise usually indicates a dead battery, try charging it first. If the motor turns but the engine doesn't start, the spark plugs may need replacing, or the fuel line could be clogged and require cleaning. It's simple to check these yourself, but if unsure, seek professional repair to avoid further damage.
