Abstract
A high voltage post terminal is accurately located within a support aperture during manufacturing processes by at least one inwardly directed projection to avoid assembly problems caused by sizing the entire aperture itself to locate the terminal with sufficient accuracy. By thus improving the concentricity of the high voltage coil components it is possible to achieve more reliable insulation between components at even relatively small-sized coils used for individual engine plug holes. An especially advantageous range of critical parameters has been discovered as achievable by using this more reliable manufacturing process.
