How to quickly find faults battery powered bike

  Repair of Flyhorse battery powered bikes in two steps, namely, troubleshooting and repair. The premise and the key is to quickly find fault repair.
 First, the car does not turn (ie, the motor does not rotate)
    1, the use of electric vehicles detector test whether the voltage of the motor leads can immediately determine the fault lines and control lines. Measurement result is voltage, then determine: bad motor or motor controller to the lead circuit fault and should be excluded. No voltage measurements, it is determined: control line failure, the next step should be checked.
     2, the brake controller plug off, and then turn the power switch to. Turn the car, then the judgment: brake switch is bad, has caused a short circuit fault, you should get a new brake switch. If the car does not turn, you then transfer to a good governor, replacing the original transfer. As the car rotates, the judgment: 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 can be judged immediately by causing the car does not turn the power section of the fault. If no voltage is displayed, turn the power locks, dashboard lights are not lit, determine: Fuse Fuse broken, should be replaced by fuses, wires off, welded wire breakage or should be renewed. If the voltage is displayed, turn the power locks, dashboard light does not shine, it is judged, power locks broken, the lock can be renewed without electricity.
 Second, turn on the power lock, turn the car stop (surprise car phenomenon), brake car
     Detection method is to control the speed regulator turn off the plug, can be determined to the governor or controller failure immediately.
 If the plug is disconnected to the governor, open the electric door lock car does not turn, determine: the governor to have been bad; If you disconnect the governor put the plug, open the electric door lock, the Flyhorse battery electric bicycle still turn, determine, control is already bad and should be replaced.
