Abstract:
1. A starter system comprising: a starter configured and arranged to be controlled by an electronic control unit, the starter further comprising: a motor coupled to a circuit; a primary plunger moveably coupled to a pinion; a first solenoid assembly comprising a plunger-return biasing member and at least two solenoid windings including a first set of solenoid windings and a second set of solenoid windings; the at least two solenoid windings at least partially circumscribing the primary plunger and configured and arranged to electromagnetically couple with and move the primary plunger to a position and to substantially retain the primary plunger in a position; a secondary solenoid assembly comprising a third set of solenoid windings 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 to be controlled by the electronic control unit, the at least two power isolation switches comprising a first switch configured and arranged to enable current to flow through the first set of solenoid windings and a second switch configured and arranged to be operated independently from the first switch to enable current to flow through the second set of solenoid windings and the third set of solenoid windings; and wherein current can flow through the second set of solenoid windings and the third set of solenoid windings irrespective of the position of the primary plunger.
