ABSTRACT:
An ignition magneto having an improved primary wiring assembly that consists of a plastic bobbin having a generally rectangular configuration and composed of a pair of end flanges connected together by a pair of side walls and a pair of end walls. The side edges of each wall are spaced from the side edges of adjacent walls, to provide a gap or slot at each corner of the bobbin. A wire is wound in a plurality of turns around the walls and extends across the slots. One end flange is provided with grooves within which the free ends of the wire are gripped. The primary winding assembly is positioned in a cup-shaped casing around a central upstanding chimney which extends upwardly from the bottom of the casing. After installing a transistor and trigger coil, as well as a secondary winding around the primary winding assembly, the components are potted in the casing with a thermosetting resin.
