Abstract: An ignition system for internal combustion engines, primarily as utilized in motorcycle type vehicles, is disclosed wherein the conventional breaker points and associated circuitry are eliminated and in their stead is incorporated a capacitive discharge circuit consisting of a step-up transformer for charging the capacitor, from a low voltage magneto, triggering circuitry to provide controlled discharge of the capacitor through the ignition transformer, and associated circuit protective components. The several components are configured in a manner such that neither the standard low voltage magneto nor the standard ignition transformer need be of special design or manufacture.
