  If your Schumacher Electric Remote Starter isn't jump-starting your car, several factors could be at play. First, ensure the clamps have a solid connection to both the battery and the frame, making sure all connection points are clean. If the connections are reversed, disconnect the jump starter and reverse the clamps. Check the charge level by pressing the Battery Status button; the LEDs will indicate the charge status. The vehicle's battery might be defective, so have it checked. Finally, confirm the jump starter is powered on by pressing the ON/OFF switch.
