Abstract
A security system for automatically disabling an interruptable circuit vital to the operation of a motor vehicle after an ignition of the vehicle is turned off or disabled. The security system includes a base circuit with a relay for disabling the interruptable circuit after the ignition is disabled. The base circuit includes a logic circuit that detects when the ignition is disabled, and for sending a disable signal to the relay. In one embodiment, the base circuit includes a timer circuit for delaying the disable signal to the relay for a specified time period after the ignition is turned off. The disabled interruptable circuit, and the disabled motor vehicle, may be enabled upon actuation of a remote transmitter, or switch on the base circuit. The base circuit also includes adapters for connecting the base circuit to the interruptable circuit and to a power supply of the motor vehicle at a fuse panel of the motor vehicle. In an alternative embodiment, the interruptable circuit and the power supply are coupled to the base circuit by splicing a wire of the interruptable circuit and the power supply circuit, and coupling the spliced wire, with an another adaptor, to the base circui…
