ABSTRACT:
Starting power supply to starter windings is interrupted whenever a power contact for the starter is still open after a predetermined time delay from initiation of the power supply to the starter. The invention also provides apparatus for controlling a contactor of a motor vehicle starter, said contactor including at least one winding and a power contact which, on being closed, serves to supply power to the starter, the apparatus including circuitry detecting the open or closed state of the power contact and for interrupting or reducing starting power supply to the winding(s) in the event the power contact is still open at the end of a predetermined time delay from initiation of power supply to the starter.
