The electric tricycle controller controls the motor. Everyone must be careful when installing the controller. The wiring should not be sloppy. It is best not to use the connector for the handlebar. It is best to connect the handlebar directly and use the insulating tape to "bundle" it. , Because the turn connector will enter the water and it will cause the car not to go or the speed will be uncontrolled. There is also a power cord, and the motor cord should be solid. It is best to solder it to avoid damage due to poor contact! At the same time, avoid the burning of the controller caused by the virtual connection or the motor cable sticking to the controller!
