ELECTRICAL SYSTEM 6 10 IGNITION SYSTEM DIGITAL IGNITOR DESCRIPTION The fully transistorized ignition system consists of a signal generator ignitor unit including 8 BIT MICROCOMPUTER and CERAMIC 4MHZ VIBRATOR ignition coils and spark plugs The charac teristic of the ignition timing is programmed and stored in the ROM READ ONLY MEMORY of the ignitor unit The signal generator comprises the rotor tip and pickup coil The signal generator is mounted at the right end of the crankshaft The induced signal in the signal generator is sent to wave form arrangement circuit and CPU receives this signal and calculates the best ignition timing from the signal of ceramic vibrator and data stored in the ROM The CPU out puts signal to the transistor of the I G coil output circuit which is connected to the primary wind ings of the ignition coil which is turned OFF and ON accordingly thus it induces the secondary current on the ignition coil secondary windings and produce the spark between spark plug gaps Ignition cut off circuit is incorporated in the ignitor unit to prevent over running engine If engine r min reaches 13 000 r min this circuit cuts off the ignition primary current for all spark plugs CAUTION Engine can run over 13 000 r min without load even if the ignition cut off circuit is effective and it may cause engine damage Do not run the engine without load over 13 000 r min at anytime Engine Side stop switch stand relay O Wo O Bo I oO Y f h Fuse 10A Battery 12V Signal generator y 10 AH B W W 4 WIRE COLOR Green G Black В White W Orange 0 R Red O W Orange with White tracer B Y Black with Yellow tracer O Y Orange with Yellow tracer O B Orange with Black tracer B R Black with Red tracer B W Black with White tracer
