Abstract: An improved glow plug controller for a diesel engine is disclosed. The glow plug controller has a novel packaging, and means for facilitating rapid and inexpensive assembly. A novel two-chamber tubular housing includes a smaller first chamber having a threaded exterior surface for engagement with a threaded hole in an engine block. This first chamber communicates with a larger second chamber also defined by the housing. A connector bearing conductive connector pins is provided for sealing the open end of the larger chamber. The connector includes a pair of support rails for engaging a piece of circuit board on which glow plug circuitry resides. In assembly, the circuit board is first mounted on the support rails which are subsequently inserted into the larger second chamber when the connector is affixed to the open end of the second chamber. The connector pins are conductively coupled to glow plug circuitry on the circuit board via portions of conductive foil on a surface of the circuit board.
