Abstract
Oil level detection sensor detects an oil level in a crankcase. First charging circuit includes a serial connection of a first charging capacitor for charging a reverse voltage produced in a primary coil, the detection sensor, and a first diode. Thyristor is turned on, in response to voltage-charging of the first charging capacitor, to disable an ignition operation of an ignition circuit. Second charging circuit includes a serial connection of a second charging capacitor for charging a forward voltage, produced in the primary coil, and a second diode. Transistor is turned on, in response to voltage-charging of the second charging capacitor, to disable a turning-on operation of the thyristor.
