Abstract:
1. A starter system comprising: a starter configured and arranged for being controlled by an electronic control unit, the starter further comprising: a motor coupled to a circuit; a plunger moveably coupled to a pinion; a first switch coupled to the circuit and configured and arranged for actuation by the plunger, the first switch comprising at least two contacts configured and arranged for electrical coupling; and wherein electrical coupling of the at least two contacts enables the flow of current through the first switch; a solenoid assembly comprising at least two solenoid windings including a first solenoid winding and a second solenoid winding; the at least two solenoid windings at least partially circumscribing the plunger and configured and arranged to move the plunger to a position and to substantially retain the plunger in a position; and wherein the second solenoid winding is coupled to the first switch and movement of the plunger can cause a coupling of the at least two contacts to substantially or completely enable current to flow through the second solenoid winding; and a secondary solenoid assembly comprising a third solenoid winding at least partially circumscribing a secondary plunger, the secondary plunger being configured and arranged to electrically couple with a set of secondary solenoid assembly contacts; and at least two power isolation switches configured and arranged for being controlled by the electronic control unit, the at least two switches including a second switch and a third switch; and wherein the third switch is configured and arranged to enable current to flow through the third solenoid winding and enable current to flow in the second solenoid winding after movement of the plunger has caused coupling of the at least two contacts of the first switch; and wherein the second switch is configured and arranged to enable current to flow to the first solenoid winding.
