Abstract

A vehicle antitheft system includes a housing connectable to the casing of a starter motor and a silicon controlled rectifier (SCR) disposed in the housing. The system includes a battery connector which engages the starter motor power line from the battery, and a starter connector which engages the power terminal of the starter motor, with the SCR being in electrical series between the connectors. A control circuit is mounted in the housing, and the control circuit closes the power switch for a predetermined period upon receipt of an enable signal from a hand-held rf generator. Consequently, the vehicle can be started by turning the ignition switch only during the predetermined period.
