Why is there no response when turning the key on a scooter motorcycle?

Reasons for no response when turning the motorcycle key: This type of failure is very common in actual repairs. In fact, the main cause of this failure lies in the connection of the battery. When troubleshooting this issue, you should first check the fuse, then inspect the tightening screws on the battery terminals, and focus on checking the connecting wires where the battery merges with the main circuit. However, battery failure cannot be ruled out. Abnormal vehicle starting: Normally, the vehicle starts successfully with one attempt, but when there is a problem with the battery or it is undercharged, starting the vehicle may require multiple attempts or may not start at all. Additionally, there may be a "squeaking" noise. Headlights dimming at idle: While driving, the headlights function normally, but when the vehicle is stopped, the headlights become less bright. This happens because the engine's charging power decreases at idle, and if the battery has issues, it cannot supply the required power to the headlights, making them dimmer when parked compared to when driving.
