    What to do if my Schumacher Electric SJ3 won't jump start my car?
    • J
      Julian Schmidt MDAug 9, 2025
      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, and that these connection points are clean. If the connections are reversed, disconnect the portable power and reverse the clamps. Check the portable power’s battery status by pressing the Battery Status button. If the battery is low, it needs charging. The vehicle’s battery itself might be defective and require a check. Finally, make sure the portable power is turned on by setting the ON/OFF switch to the ON position.

    Why won't my Schumacher Electric SJ3 Remote Starter power my 12V device?

      Amy Reese MDAug 19, 2025
      If your Schumacher Electric Remote Starter isn't powering your 12V device, there are a few potential reasons. Start by ensuring the 12V device is switched on. Check the portable power's battery charge status by pressing the Battery Status button. If the battery is low, charge it. Also, the 12V device might be drawing more than 15A or have a short circuit. In this case, disconnect the 12V device and wait a minute or two for the internal breaker to automatically reset, then try the 12V device again.
