  If your Schumacher Remote Starter won't jump start your car, here are a few things to check: * Ensure the connections are not reversed. If they are, disconnect the portable power and reverse the clamps. * Make sure the clamps have a good connection to the battery and frame, and that the connection points are clean. * Check the battery status of the portable power by pressing the Battery Status button. The LEDs will indicate the charge status. If the battery is low, charge it. * The vehicle's battery may be defective; have it checked. * Verify that the portable power is turned on by setting the ON/OFF switch to the ON position.

  If your Schumacher Remote Starter isn't powering your 12V device, consider the following: * Ensure the 12V device is turned on. * Check the portable power's battery charge by pressing the Battery Status button. * The 12V device might draw more than 20A or have a short circuit. If so, disconnect the 12V device. A qualified service person needs to replace the internal 20A fuse.
