Why doesn't the Dayang electric four-wheeler move when it has power?
3 Answers
Dayang electric four-wheeler not moving despite having power is generally due to switch issues or fuse box failure. Switch failure: Power-off switch damage or failure to reset is the most common issue. If it's a brake spring or switch reset problem, it can usually be directly seen as a prompt on the LCD display. Switch spring: Power-off switch spring damage or foreign object obstruction. This can generally be checked by observing whether there are foreign objects near the foot brake or if the spring is damaged. Remove any foreign objects; if the spring is damaged, repair is needed. Fuse box: If the vehicle has power when the key is turned but doesn't move, while headlights and horn work normally, generally check if the main fuse in the fuse box controlling the key line is damaged. If damaged, replace it.
When my electric car has power but doesn't move, it's usually due to the battery's overstated capacity leading to insufficient power, where the actual charge might only be enough for display but not for driving. Check if the battery connections are loose or oxidized, which is common in older cars with battery degradation. Another issue could be the controller, which acts as the brain, distributing current to the motor; if it's damaged, the car won't move. Don't forget to check if the brakes are stuck, or if safety locks like the handbrake or key switch aren't properly engaged. It's recommended to first use a multimeter to test the voltage—replace the battery if it's below the standard—or take it to a repair shop to check the controller. Remember, timely action ensures safety.
When encountering an issue where an electric vehicle has power but won't move, it's often due to motor failure or circuit short circuits. The battery shows full charge, but the output is unstable, affecting the drive. Simple self-checks include observing if the dashboard is functioning normally and testing if gear shifting is responsive; if the motor hums but doesn't move, it might be burnt out. Also, pay attention to blown fuses or poor plug contact, as these small details are easily overlooked. It's best not to force it to operate to avoid further damage. Regular maintenance can prevent these issues.
