1. A glow plug controller for a motor vehicle diesel engine comprising:

  • a) an electric power source mounted to the motor vehicle for providing a power supply signal;

    b) glow plug controller circuitry powered by the power source for determining a glow plug pre-combustion preglow energization cycle for heating one or more glow plugs;

    c) a monitor coupled to the glow plug controller for providing a signal indicative of a voltage output of the electric power source;

    d) a switching device coupled to the glow plug controller and the electric power source for energizing the one or more glow plugs for the preglow energization cycle prior to initiating combustion in the diesel engine; and

    e) said glow plug controller including an adaptive control program for adjusting the preglow energization cycle during which the one or more glow plugs are energized prior to combustion, the preglow energization cycle being adjusted based on the voltage output of the electric power source.
