<p>A solenoid in an engine starter assembly includes an electromagnetic coil operable on a plunger coupled to a shift lever to move a pinion gear into contact with the engine ring gear. The solenoid is provided with a return spring to restore the plunger to an initial position in which the pinion and ring gears are disengaged, in the absence of a coil force. A contact plate is supported on the plunger to engage open electrical contacts when the plunger is in a first position to complete an electrical circuit to drive the starter motor rotating the pinion gear at a faster speed. An over-travel spring resists movement of the plunger once the contact plate engages the electrical contacts. An auxiliary spring is disposed on the plunger to resist movement of the plunger only when the plunger travels to a position offset between the initial position and the first position.</p> |
