① Check whether the
Used Car battery output is normal. If the output is too low, it means the battery is bad. The battery needs to be replaced urgently.

③Check the steering wheel and use iron wire to short-circuit the steering wheel and the signal line. If the car rotates, it proves that the steering wheel is broken and needs to be replaced or repaired. Turn on the power, turn the knob, and use a multimeter to measure the positive and signal wires.
④If the controller is good or bad, you can use the positive 5V short circuit of the handlebar wire. If the handlebar rotates, it means there is no problem with the controller.
