Claim 8:
9. A method for providing multi-mode electrical power to a load in a vehicle having a first voltage source and a second voltage source, the load having a first side and a second side, the first voltage source having a positive side and a negative side, and the second voltage source having a positive side and a negative side, the method comprising:
connecting a main positive relay having a first side and second side to the vehicle load by connecting the second side of the main positive relay to the first side of the load;
connecting a main negative relay having a first side and second side to the vehicle load by connecting the second side of the main negative relay to the second side of the load;
connecting a first relay having a first side and a second side to the first voltage source and the second voltage source by connecting the first side of the first relay to the positive side of the first voltage source and connecting the second side of the first relay to the negative side of the second voltage source;
connecting a second relay having a first side and a second side to the first voltage source, the second voltage source, and the main positive relay by connecting the first side of the second relay to the positive side of the first voltage source and connecting the second side of the second relay to the positive side of the second voltage source and the first side of the main positive relay;
connecting a third relay having a first side and a second side to the second voltage source and the main negative relay by connecting the first side of the third relay to the negative side of the second voltage source and connecting the second side of the third relay to the first side of the main negative relay;
wherein each of the first, second, and third relays is independently operable between an open position and a closed position; and
providing electrical power from the first voltage source and/or the second voltage source to the vehicle load according to one of a plurality of operating modes by opening or closing each of the first, second, and third relays.
