ABSTRACT:
An anti-theft battery system for vehicles includes a control circuit which is connected in the starting circuit and responds to a starting current which exceeds a set point value to interrupt the starting circuit, thereby disconnecting the starter motor from the battery preventing starting of the vehicle, a reset circuit responsive to the control circuit which resets the control circuit after a delay interval to permit the starter motor to be connected to the vehicle battery, and an override circuit for generating an override signal for overriding the control circuit for a preselected interval of time to permit an authorized operator to start the vehicle, the override circuit including a small portable transmitter adapted to be carried by the vehicle operator and a receiver connected to the control circuit.
