1. A circuit for providing multi-mode electrical power to a load in a vehicle, the circuit comprising:
a first voltage source having a positive side and a negative side;
a second voltage source having a positive side and a negative side;
a main positive relay having a first side and a second side, the second side of the main positive relay connected to a first side of the load;
a main negative relay having a first side and a second side, the second side of the main negative relay connected to a second side of the load;
a first relay operable between an open position and a closed position, the first relay having a first side and a second side, the first side of the first relay connected to the positive side of the first voltage source, and the second side of the first relay connected to the negative side of the second voltage source;
a second relay operable between an open position and a closed position, the second relay having a first side and a second side, the first side of the second relay connected to the positive side of the first voltage source, and the second side of the second relay connected to the positive side of the second voltage source and the first side of the main positive relay; and
a third relay operable between an open position and a closed position, the third relay having a first side and a second side, the first side of the third relay connected to the negative side of the second voltage source, and the second side of the third relay connected to the first side of the main negative relay.
