Abstract

An arrangement for protection against abnormal currents in a starter motor circuit of a starter motor (1) connected to an internal combustion engine of a motor vehicle has a sensor (13) sensing the presence of a start control signal sent to the starter motor, a member (17) measuring a quantity indicative of the current fed into the starter motor and a control unit controlling a device (24) to break the current fed to the starter motor if a current to the starter motor is measured in spite of a lack of a said start control signal.
