Abstract A vehicle theft prevention system for locking the hood of a motor vehicle while simultaneously disconnecting the vehicle battery from the vehicle electrical circuitry. A locking shaft member is movable by insertion of a key in a lock mounted on a vehicle hood. A plate member mounted on the shaft prevents the vehicle hood from being raised when the shaft is in a first position, and enables the hood to be raised when the shaft is moved to a second position. An electrical switch armature is mounted on a second shaft for disconnecting the vehicle battery from the vehicle electrical circuitry when the shaft is in the first position and connecting the vehicle battery to the vehicle electrical circuitry when the shaft is in a second position. The electrical switch armature interconnects a pair of terminal members formed of flared spring fingers which provide an interconnection between portions of the battery cable when it is desired to operate the vehicle. The first and second shafts are gauged to rotate together by a separable interconnection for enabling the hood to be raised when the vehicle engine is running.
A vehicle theft prevention system for locking the hood of a motor vehicle while simultaneously disconnecting the vehicle battery from the vehicle electrical circuitry comprising: a shaft member movable by insertion of a key in a lock mounted on the vehicle hood; a plate member secured to said shaft for preventing the vehicle hood from being raised when said shaft is moved to a first position and enabling said hood to be raised when said shaft is moved to a second position; and switching means mounted on said shaft for disconnecting said vehicle battery from said vehicle electrical circuitry when said shaft is in a first position and connecting said vehicle battery to said vehicle electrical circuitry when said shaft is in a second position.
