      If your Schumacher Remote Starter isn't jump-starting your car, several factors could be at play. First, check that the connections aren't reversed; if they are, disconnect the jump starter and reverse the clamps. Another cause might be that the jump starter's battery is not charged. In this case, check for a poor connection to the battery and frame, ensure the connection points are clean, and press the Power button on the front of the unit to check the charge status via the LEDs. The issue may also stem from a defective vehicle battery, which would require a professional check. Lastly, make sure the jump starter is turned on by pressing the Jumpstart/Override button.

      If your Schumacher Remote Starter isn't operating, it could be due to a low internal battery voltage. To resolve this, use either the wall charger or the car charger to charge and activate the device.
