Freight electric bike motor does not turn, how to deal with

the car does not turn

    1, the use of cargo electric bikes detector test whether the voltage motor leads, can immediately determine the fault lines and control lines. There is a voltage measurement, it is determined that: bad motor or controller circuit failure of the motor to the lead, should be excluded. No voltage measurements, it is determined that: the control circuit is faulty, the next step should be checked.

    2, the cargo electric bicycles brake controller plug disconnected, then turn the power switch to. Car rotates, it is determined that: the brake switch is bad, has been causing a short circuit fault, the brake switch should be renewed. If the car does not turn, then a good governor and then turn to, turn to replace the original. Such as the car rotates, it is determined that: the original to the governor is bad, causing the electric car does not turn, should get a new controller.

    3, measuring the battery compartment contacts, the power supply section can be determined immediately because the car does not turn cause failure. If no voltage display, turn the power locks, dashboard does not light up, it is determined that: Fuse Fuse off, should be replaced by fuses, wires off, welding wire breakage or should be renewed. If voltage display, turn the power locks, dashboard light does not shine, it is determined, power locks broken, no power to get a new lock.
