How to judge whether the Tricycle With Cabin controller is short-circuited or the motor is flooded

When it cannot move, turn the motor wheel by hand to see if there is any obstruction. If there is no abnormality when walking, it means that the motor is fine. It should be that the controller plug has water in it. This is more common. First unplug the power source to find the controller, unplug the plug and shake off the water, then wipe it with a dry towel and then plug it in. Be careful to do it one by one, don't plug it in the wrong way. If it works normally, it means that there is no problem.

Our approach: Use the DC voltage range of the multimeter to connect to the socket of the Tricycle With Cabin charger to check the battery voltage. The voltage must be normal when the Tricycle With Cabin is not riding. Increase the ignition key, the voltage drops to about 42V, the motor shakes, and the speed drops rapidly. The reason is the battery. If the battery box fuse and the battery are well connected, then the battery is finished.

When the ignition key is increased, the voltage hardly drops, and the front position indicates that the voltage drops, the motor stops and runs, and the lock control switch and its circuit reasons; when the ignition key is increased, the voltage hardly drops, and the front position indicates that the voltage does not drop either, and the motor stops and runs, which is the controller current protection; the common thing is that the protection resistor in the controller is unsoldered.

Don't trust the dial information of your Tricycle With Cabin completely, it is not accurate.
