Why won't my MasterForce 260-9517 jump start my car?
- JJennifer BestAug 5, 2025
Your MasterForce Remote Starter might fail to jump start your car due to several reasons: * Poor connection to the battery or frame. Ensure connection points are clean. * Reversed connections. Disconnect the jump starter and reverse the clamps. * The unit's battery is not charged. Check the charge status by pressing the Battery Status button. * Defective vehicle battery. Have the battery checked. * The unit is not turned on. Turn the unit's ON/OFF switch to the ON position.
