Main Relay testing and replacement at home. A main relay is a device that opens and shuts the fuel system and in most cars, it also opens and shuts the ignition system. It gives power to your vehicle's most electrical components, like the engine control unit and other modules. When you turn your vehicle on, it shifts the relay to a new position, which allows you to start your vehicle by sending power to the necessary components.
