Why does the electric scooter's lights turn on but it doesn't move when twisting the throttle?

[OJoanna]

Here are the reasons why the electric scooter's lights turn on but it doesn't move when twisting the throttle: Blown fuse: Replace the fuse. Faulty power switch: Replace the power switch. Damaged Hall throttle: Use a multimeter to measure the DC voltage output from the green wire at the throttle output terminal. If there is a 1-4.2V output, the throttle is normal. If there is no voltage output, the throttle is burnt out and needs replacement. Damaged controller: Use a multimeter to measure the DC voltage output from the red wire at the controller output terminal (connected to the throttle wire plug). If there is approximately 5V output, the controller is normal. If there is no voltage output, the controller is burnt out and needs replacement. Burnt power cut-off switch: If all the above possibilities are ruled out, unplug the power cut-off switch connector. If the motor runs normally, replace the power cut-off switch.
