Reasons for continuous running

Most electric scooter speed controllers use MOSFET transistors to control the speed of the motor. When these types of transistors burn out, they lock the power supply in the on position, causing the motor to continuously run at full speed.

Fault factors and solutions

Factors	Troubleshooting	Solutions
Speed controller fault	First disconnect the throttle from the speed controller. If the motor stops, the throttle is faulty. If the motor continues to run, the speed controller is faulty.	If the throttle is faulty, replace the throttle If the speed controller is faulty, replace the speed controller.
