ABSTRACT:
The energizing circuit of one of the primary windings of an ignition coil having at least two primary windings and a secondary winding is interrupted in timed relationship with the engine whereby a high ignition arc-creating potential is induced in the secondary winding upon each interruption of the primary winding energizing circuit. Upon each interruption of the primary winding energizing circuit, a monostable multivibrator circuit is triggered to the alternate state in which a potential signal is present upon the output circuit thereof and an electrical switching device is triggered conductive to complete a discharge circuit for an ignition capacitor through the other ignition coil primary winding. A charge potential generating circuit under the control of the potential output signal of the monostable multivibrator circuit operates to produce a direct current charge potential in response to the termination of the potential signal and to impress the direct current charge potential across the ignition capacitor.
