Abstract
In a method of controlling energisation of the coil of a motor vehicle starter contactor the coil is energised in a pick-up mode to close the contactor and then in a latching mode to hold the contactor closed. A voltage corresponding to the supply voltage of the electric motor of the starter is measured, a drop in this voltage corresponding to the closing of the contactor is detected, and the coil of the contactor is energised in latching mode after a predetermined time-delay from detection of the voltage drop.
