Abstract
A method of making a unitary spark distribution cassette involves molding a cassette and placing electrically conductive lead frames within the cassette during molding. Electrically conductive sleeves for fitting over spark plugs are also provided on the cassette. An ignition system circuit using high voltage diodes in conjunction with an alternating flux ignition coil is placed in the cassette and connected to the lead frames and the sleeves to create a complete electrical circuit. The cassette is then filled with epoxy resin to encase the electrical components to form a unitary package.
