<p>This invention relates to a disabling system for a vehicle having an electrical ignition circuit. Such ignition circuits have an open-circuit mode in which the vehicle is de-energized, and a closed circuit mode in which the vehicle can be driven by its engine. The disabling system according to the invention when in the vehicle is operative to move the electrical ignition circuit to the open circuit mode only after the circuit has been in a closed circuit mode for a pre-determined time interval. Thus the vehicle engine can be powered, but then the engine cuts out, thereby preventing a thief from moving the vehicle any great distance. In a preferred embodiment the ignition circuit is coupled to the fuel gauge such that the apparent cuase for the engine cut out is lack of fuel.</p> |
