Why VEVOR EJ3550B motor will not operate?

  Several factors can prevent the motor from operating: * **No or low voltage:** Check the battery and electrical connections, ensuring a minimum of 10 VDC. If the battery is low, connect the trailer cable to the tow vehicle and start the tow vehicle to supply power. * **Poor grounding:** Ensure direct metal-to-metal contact between the jack mounting plate and coupler by cleaning the area and removing paint with star washers. * **Loose wires on ON/OFF switch:** Secure all wire connections. * **Faulty ON/OFF switch or motor:** Replace the switch or the motor.
