Children's electric vehicle maintenance tutorial

1. First, check whether there is an output terminal welded on the battery, then check whether the fuse and the safety platform are good or bad, and finally check whether the power lock is good or bad and whether the output of the battery of the electric vehicle is normal. If the low output power proves that the battery is broken, please replace the battery and unplug the brake cable. If the rotating steering wheel proves that the steering wheel is broken, it must be replaced or repaired. If the steering wheel is checked and shorted with wire, turn the positive pole and signal line of the steering wheel, such as the steering wheel of an automobile, to prove that the steering wheel is broken, and replace or repair it as soon as possible. Turn on the power supply, turn the handle, and use universal instrument. There are handles with positive 5v < 1-4 > on the positive pole, cable and signal line. Short-circuit the steering wheel with one plus 5V, rotate like the steering wheel, and use the simplest method to explain whether the controller has burnt smell, which proves that the controller is damaged and the motor is good or bad.

2. Check whether the motor is good or bad. The contact of the motor carbon brush is uncertain, which is a bit awkward. How to repair with motor for children [Brushless and Brushless]: Brushless motor is measured with universal gauge, and it is proved that the motor is good after passing the test. Failing is not a bad thing. The eight lines of the brushless motor are respectively black, red, yellow, green, blue, rhubarb, big green and big blue, and the black lines of the red pen motor after using the instrument are blocked by the three lines of black pen respectively by 650-750.

3. Before opening, please pay attention to whether the friction between the exchanger and the carbon brush is empty. If so, please rub it with sandpaper, turn on the motor, keep the distance between the exchanger and the carbon brush, and be careful not to let the wire wrap of the motor rub the wire wrap, so as to avoid the wire wrap being damaged. Please stick the magnet steel with iron east and west to prevent the magnet steel from cracking. When replacing the brushless motor, attention must be paid to the contact of Hall wood wire. For the first time, it is best to remove the wire and weld another one to avoid welding errors. After welding, first fasten with AB rubber at 502 to avoid the phenomenon of looseness. Please install the magnetic steel on the magnetic steel, clean the rubber on the spindle and the magnetic steel, absorb it with the magnetic steel and the magnetic steel, and pay attention to adding the rubber in the opposite direction before sticking together.

4. Turn on the door lock power, and the power indicator of the instrument panel does not light up. Turn the handle without turning the motor, adjust the fuse on the battery case to burn out (replace the fuse, fuse tube on the battery case has poor contact), make the contact piece have poor contact with the battery case, make the contact piece of the battery case burn out the door lock), replace the new door lock, the battery wire in the battery case is broken), connect the circuit to update, and the door lock wire or contact wire is broken or poorly contacted), and reconnect.
