What to Do When an Electric Vehicle Shakes and Fails to Move?

[MacDerek]

Here are the solutions for an electric vehicle that shakes and fails to move: 1. Battery: Check if the battery output is normal. If the output is too low, it indicates a faulty battery that needs immediate replacement. 2. Controller: To test the controller, short-circuit the positive 5V of the throttle wire. If the throttle turns, the controller is fine. The simplest method is to smell for any burnt odor from the controller. 3. Throttle: Inspect the throttle by short-circuiting the positive and signal wires with a piece of wire. If the vehicle moves, the throttle is faulty and needs immediate replacement or repair. Turn on the power and use a multimeter to measure the positive and signal wires while twisting the throttle. 4. Motor: Check the motor's condition. Poor contact of the motor's carbon brushes can also cause the vehicle to have power but not move. 5. Brake: Disconnect the brake wire. If the vehicle moves, the brake handle is damaged and needs replacement.
