Electric lawn mower which brand is good 48 V battery car charging
Measuring the battery box contacts, can be immediately judged by the power part of the car does not turn the fault. If there is no voltage display, turn on the power lock, dashboard indicator light is not bright, then determine: fuse fuse broken, should change the fuse, wire off, broken head or should be replaced. If there is voltage display, turn on the power lock, dashboard indicator light does not shine, then determine the power lock is broken, can not change the new lock.
Detection method is to turn off the controller regulator speed switch, you can immediately determine the speed switch or controller failure. If you disconnect the speed switch handle, open the door lock car does not turn, and determine: speed switch has been bad; if you disconnect the speed switch, open the door lock, the car also turn, determine, control The device is bad and should be changed.
Disconnect the controller brake plug and turn the electric turn. Car rotation, then determine: brake switch has been bad, has caused short-circuit fault, should be a new brake switch. If the car does not turn, then use a good speed switch, replace the original turn. Such as car rotation, then determine: the original speed switch has been bad, resulting in battery car does not turn, should replace the new controller.
Use the battery car tester to test whether the motor lead voltage, can immediately determine the line and control circuit failure. If the voltage is measured, it is judged that the motor is broken or the fault of the controller to the motor is broken. If the measurement result is not voltage, it is judged that the control circuit is faulty and the next step should be checked.
Battery car in the use of the process, it will inevitably occur "strike" phenomenon, know the basic maintenance of common sense, so you worry a lot. Repair the battery car in two steps, that is, find the fault and repair. The premise of repair and the key is to quickly find the fault, find out the cause of the failure, and then to repair.
