Abstract
PURPOSE:To prevent the over-rotation and enhance maneuverability by a method wherein an ignition circuit is made to be inoperative by a misfire circuit at the time of over-rotation, said misfire circuit being made to be inoperative by an operation signal of a brake lever. CONSTITUTION:At the time of over-rotation, a backward voltage generated by a pluser coil 2-2 exceeds the voltage of a Zener diode 14, so that a transistor 15 is turned ON and a capacitor 16 is charged. The charge on the capacitor 16 turns a transistor 17 on so that a thyristor 18 is made to conduct, causing the ignition circuit to be inoperative. At the time of engine starting, a transistor 21 in a flip- flop (FF) 19 is ON, and when a brake lever switch 7-1 is turned ON, a transistor 20 in the FF 19 is turned ON and a transistor 25 is turned ON, whereby the thyristor 18 is made to be inoperative so that the misfire circuit cannot operate. Accordingly, the over-rotation can be prevented, and the running can be enabled by merely operating the brake lever.
