A machine includes a plurality of electronic controllers electrically connected to an electrical power source along a first electrical circuit through a first relay and along a second electrical circuit through a second relay. A relay controller is directly connected to the electrical power source along a third electrical circuit, and is in communication with the first relay and the second relay. The relay controller is configured to open or close the first relay or the second relay in response to a power requirement indication.
