PURPOSE:To prevent power supply voltage drop, surge voltage, and noise by providing an exclusive battery for a microcomputer or an ignition unit, which requires stable electric current, in a manner that said battery is disconnected from another battery for a starting motor or an electric load. CONSTITUTION:When key-switches 5 and 5a are closed, a field coil 2 and an ignition coil 10 are electrified. And when an engine 11 rotates, an igniter 9 operates and the engine starts operation. Various informations form the engine 11 is entered in a microcomputer 12 from a sensor 13, and an actuator 14 operates to control the engine 11. The second battery 6a is charged by an electric power supply 100 like a solar battery, other than a generator, through a non- return diode 101. When the engine rotates, an armature coil 1 generates an AC output that is converted into DC by means of a rectifier 3. And a voltage regulator 4 regulates the current in the field coil 2 so that the first battery, too, can supply an electric load 8 with electric power, while keeping the terminal voltage constant. |
