ABSTRACT:
An anti-theft device for an automotive vehicle or any internal combustion engine turned over by a starter, in which electrical energy is connected to the starter only at such times as several rotatable digital members are arranged in selected positions. The digital control means may be positioned in either of two alternative coded positions to energize the starter depending upon the position of a hidden switch which the user manipulates according to the particular code he desires.
The digital means are connected to the starter such that an unauthorized "hot wire" creates a short circuit for the thief. Similarly, the ignition coil is so wired as to provide a short circuit if the thief should attempt to hot wire the ignition coil.
