ABSTRACT:
In a system for cranking a crankshaft of an internal combustion engine, a starter is provided with a motor working to, when energized, rotatably drive an output shaft with a pinion and an actuator working to, when energized, shift the pinion toward the ring gear to be engaged with the ring gear. A power supply is electrically connected to the motor and operative to output electrical power. A first mechanical relay is electrically connected between the power supply and the motor, and works to turn on and off a supply of a current based on the electrical power to the motor for rotating the pinion. A switching element is electrically connected across the first mechanical relay, and works to turn on and off the supply of the current to the motor for rotating the pinion.
