3. Battery box - check whether the welding wire is broken and whether the spring is in good contact with the battery.

4. Test the switch circuit to see if the micro switch is energized or not. If it is energized, it means that there is no problem with the switch. If it is not energized, please replace the micro switch.

5. The main board of the circuit, if all the above problems are checked, the main board must be replaced.
