Why does the Haoyu electric vehicle suddenly stop moving?

[ParkerLee]

There are many reasons why the Haoyu electric vehicle may stop moving. Main reasons why the Haoyu electric vehicle stops moving: Check if the battery output is normal. If the output is too low, it indicates battery damage and the battery needs to be replaced; if the brake handle cable is broken and the wheels rotate, it means the brake handle is faulty and must be replaced; check the throttle handle by shorting the positive and signal wires with a wire—if the vehicle moves, the throttle handle is faulty and needs replacement or repair. Turn on the power and twist the throttle handle, then use a multimeter to measure the positive and signal wires; check if the controller is damaged by shorting the positive 5V wire of the throttle handle—if the throttle handle moves, the controller is fine. The simplest method is to smell for a burnt odor from the controller. If present, it indicates controller damage and replacement is needed; check if the motor is damaged. Loose motor carbon brushes can also cause the vehicle to have power but not move. It is recommended to visit a repair shop for maintenance or replacement. Other possible reasons why the Haoyu electric vehicle stops moving: Damaged Hall sensor inside the accelerator (throttle), recommended replacement; the brake cut-off system is stuck or not reset, simply reset it; control circuit is broken or the controller has a fault, replace necessary components; motor failure, recommended to visit a repair shop for inspection and repair.
