ABSTRACT:
A glow plug controller for diesel engines includes a two-chamber housing, with a low-level control circuit module in a first chamber and a high-level switching means in the form of a relay or contactor in a second chamber, so that the controller can be repaired or modified by replacement of a single module, and heat generated in one chamber has no effect on the other chamber. The controller is adapted for use with positive-temperature-coefficient glow plugs, and includes at least one temperature-actuated switch means and a second relay means, functioning respectively as timer means and lockout means. An overvoltage switch and a wait-lamp switch may also be provided. The low-level control circuit includes a connector insert portion molded into an insulating block, which is severed through apertures in the insulating block to define appropriate circuit elements for mounting series-connected switch means to the circuit elements.
