<p>An ignition system having a first primary coil (40) magnetically coupled only to a first secondary coil (42) and a second primary coil (50) magnetically coupled only to a second secondary coil (52). The secondary coils (42,52) are electrically coupled to the output terminals (12,32) through a diode steering circuit (78,82,86) for connecting both secondary coils (42,52) in voltage-aiding series such that the sum of the voltages on both secondary coils is coupled across the output terminals (12,32) when both primary coils (40,50) are simultaneously actuated; only the first secondary coil (42) is coupled across the output terminals when only the first primary coil (40) is actuated; and only the second secondary coil (52) is coupled across the output terminals when only the second primary coil (50) is actuated.</p> |
