ABSTRACT:
A first device is provided for selectively activating and deactivating a glow plug. A microcomputer system is connected to the first device for controlling the first device. A DC power source is electrically connected to the microcomputer system and a starting motor for supplying DC electrical power to the microcomputer system and the starting motor to activate them. The microcomputer system becomes inactive and causes the first means to deactivate the glow plug when the voltage of the DC electrical power drops below a minimum rating value. A switch is disposed in the electrical connection between the starting motor and the power source for selectively effecting and interrupting activation of the starting motor. A second device is provided for activating the glow plug when the switch effects activation of the starting motor regardless of whether or not the voltage of the DC electrical power drops below the minimum rating value.
