PURPOSE:To prevent re-start of an engine in the event that a kill switch remains in an unreturned position after temporary stop of the engine, by providing a relay designed to be turned on by a kill switch and to be turned off by an on- operation of a starter switch and thereby controlling current feed to an ignition unit. CONSTITUTION:When a kill switch 7 is turned on, a first transistor (a) is turned on and is held under on condition by a switching operation of a relay switch 6b to its contact point B. Thus, a relay 6 self-holds stoppage of current feed to an ignition unit. When a starter switch 4 is turned on and the first transistor (a) is turned on, the self-hold of the relay 6 is released to switch the relay switch 6b to its contact point A, thereby permitting current feed to the ignition unit 5. In this manner, even when the kill switch remains in an unreturned position, it is possible to start an engine. |
