ABSTRACT:
An ignition system having a first primary coil magnetically coupled only to a first second coil and a second primary coil magnetically coupled only to a second secondary coil. The secondary coils are electrically coupled to the output terminals through a diode steering circuit for connecting both secondary coils in voltage-aiding series such that the sum of the voltages on both secondary coils is coupled across the output terminals when both primary coils are simultaneously actuated; only the first secondary coil is coupled across the output terminals when only the first primary coil is actuated; and only the second secondary coil is coupled across the output terminals when only the second primary coil is actuated.
