ABSTRACT:
A improved stator apparatus for use in the ignition system of an internal combustion engine. The stator apparatus comprises a magnetically permeable core having a coil housing mounted to a leg portion thereof. A coil assembly including a voltage transformer is maintained in the coil housing. The various coils of the coil assembly are mounted about a central chimney member of the housing coaxial with the portion of the core extending therethrough. A circuit grounding member is electrically connected between the voltage transformer and the core by frictional contact therebetween. The circuit grounding member is constructed of a generally flat conductive piece having a longitudinal ridge defined along a portion of its length. In exemplary constructions, the longitudinal ridge extends along side a portion of the core and is biased into frictional contact therewith. The ridge facilitates assembly of the stator apparatus as well as enhancing electrical connection of the grounding member with the core.
