ABSTRACT:
An electrical antitheft system for a motor vehicle inhibits the power supply to the ignition circuit of the vehicle, by preventing the engine from starting so long as the motor that actuates a blocking member of the antitheft system has not reached the unlocked position. The logic functions for controlling locking and unlocking of the system are obtained through a wired and protected logic system that connects the power supply terminals of the motor of the antitheft system to the poles of the battery through a pair of switches.
