Claim:
1. An electrical system comprising: an engine; a motor-generator; a starter mechanism; a first energy storage device having a first voltage level; a second energy storage device having a second voltage level less than the first voltage level; a first switching device selectively transitionable between a first open state and a first closed state; a second switching device selectively transitionable between a second open state and a second closed state; a controller including a processor and a memory having recorded instructions, wherein the controller is configured to control the motor-generator, the starter mechanism and the first and second switching devices, and wherein current from at least one of the first and second energy storage devices is delivered to the motor-generator when at least one of the first switching device is in the first closed state and the second switching device is in the second closed state such that the motor-generator transfers torque to the starter mechanism and the starter mechanism uses the torque to start the engine.
