Abstract

A system for cranking an internal combustion engine includes an electric starter and a current supply circuit having a key switch. By turning on the key switch, the starter is rotated to crank the engine. To avoid an inadvertent restart of the starter while the engine is running, a locking device that prohibits the inadvertent turning-on of the key switch is provided in the system. A starter relay may be included in the current supply circuit. The starter relay is kept open even if the key switch is turned on when the engine is running to prohibit the inadvertent restart of the starter.
