secondary windings of the ignition coil accordingly the height of the ignition coil 228 is reduced from that of the ignition coil components in fig1 and 2 the height factor and volumetric space gained as a result of the removal of these components allows space for the printed circuit card 226 and the associated circuitry components for positioning in a housing that is similar to the housing 120 of fig7 atop the ignition coil 228 thus the overall dimensions of the housing to incorporate the capacitor discharge ignition system of fig1 is substantially similar to that of the housing to incorporate the prior art arrangement of fig1 and 2 ease of manufacture is obtained by the arrangement of fig1 and 15 by allowing the automated or semi automated mounting of the circuitry components on the printed circuit card 226 and ease of assembly of the overall capacitor discharge ignition system the further cost reduction of the overall capacitor discharge ignition system is also made possible by the reduction of the wire content of the ignition coil 228 as determined by the size of the charging capacitor 34 of fig4 and the desired volumetric dimensions of the housing to incorporate the capacitor discharge ignition system of fig1 and 15 the capacitor 34 may be mounted either within the housing with the circuitry components 242 on the printed circuit card 226 or alternatively may be positioned directly atop the printed circuit card 226 and potted therewith during the potting phase to complete the capacitor discharge ignition system after mounting in the housing in another alternative arrangement the capacitor 34 may be mounted externally by means.
