Why doesn't the electric scooter move when accelerating after being rained on?

This situation may occur due to a circuit break or possible controller damage. Immediate professional repair is required when this happens. Electric vehicles have numerous circuits, and rain exposure may cause battery circuit short circuits, preventing normal operation. Here's additional information: Electric Vehicles: An electric vehicle is a transportation device with a simple structure. Its main components include the frame, motor, battery, and electronic control system. The electronic control system is essentially the controller, which manages all vehicle circuits. Without the controller, the electric vehicle cannot operate normally.
After riding my electric bike in the rain last time, it also broke down. The dashboard was lit, but it wouldn't move when I twisted the throttle. First, I checked three places: Was the air switch under the seat tripped? Many bikes automatically cut off power for protection when they get wet. Then I opened the throttle wire harness connector, and sure enough, there were water droplets inside. After drying it, I wrapped it in a plastic bag for moisture protection. The most troublesome part was the controller, the aluminum box under the foot pedal. When I opened it, I found the circuit board was covered in condensation. I used a hair dryer on the cold setting for ten minutes before daring to put it back. By the way, it's also important to check the Hall sensor interface of the hub motor. If the metal contacts rust due to water, they can misread speed signals. For such issues, it's best to add waterproof covers, which cost about ten yuan for three on Taobao.
Riding in the rain can indeed cause this issue, my little e-bike had the same problem last month. Focus on checking the controller and wiring connectors, especially the main harness plug under the seat bucket which is most prone to water ingress and short circuits. Here's a temporary fix: disconnect the battery for half an hour before reconnecting to reset the controller's protection program. If that doesn't work, you'll need to check the throttle signal wire—measure the output voltage with a multimeter; it should fluctuate normally between 1.1-4.2V. By the way, here's a lesser-known fact: many bikes experience motor phase angle misalignment after getting wet in the rain and require a shop visit for decoder rematching.
Lights on but scooter won't move after getting wet? Most likely the controller activated waterproof protection. First, squeeze the brake and toggle the power switch ten times - some models allow forced reset. Check the dashboard for error codes; a constantly lit throttle icon indicates speed controller issues. Open the throttle to dry the three magnetic sensors inside, then apply Vaseline to the sealing ring. The waterproof sponge at the controller's heat vent is critical - when waterlogged, it blocks airflow causing overheat protection. Worst case scenario: damaged motor Hall sensor, evidenced by clicking sounds when pushing the scooter.
