Abstract
An electronic ignition control system including one coil assembly having a high number of turns to charge the associated capacitors to a desired level when the speed of the engine is low, and another coil assembly having a low number of turns to charge the capacitors to a desired level when the speed of the engine is high to thereby provide energy at a suitable level to fire the associated spark plugs. The system also includes means for regulating the voltage supplied by the alternator coils to a battery and thus preventing the battery from overcharging; and, means are provided for driving a tachometer proportionally to the firing pulses supplied to the spark plugs.
