Abstract
Abstract A vehicle ignition theft control system for vehicles having a conventional ignition system and a capacitive discharge ignition system for controlling current flow through the primary winding of an ignition coil. Means are provided for operatively connecting either the conventional or CD ignition system to the primary winding of the ingition coil. The electrical connection of the selected ignition system to the primary winding of the coils achieved by means of a two position, substantially planar, removable jumper or ignition "key." The planar "key" has a first plurality of jumper elements on the front surface and a second plurality of jumper elements on the back surface. The jumper elements form a first predetermined pattern of electrical connections when the jumper is in a first position and a second predetermined pattern of electrical connections when the jumper is in a second position. The second position is obtained by flipping over the planar jumper. In the preferred embodiment, the output of the CD ignition system is directly connected to the primary winding of the ignition coil without utilizing any of the jumper elements. The vehicle battery is connected to the primary winding of the ignition coil in the conventional ignition system mode through a set of contacts on a relay. Energization of the relay is controlled by at least one jumper element on the "key."
