Abstract
A solenoid for a vehicle starter includes a pull-in coil made of a length of rectangular wire and a hold-in coil adjacent to the pull-in coil. A plunger is configured to move in an axial direction when the pull-in coil made of rectangular wire is energized. The pull-in coil and the hold-in coil are positioned on a spool with the plunger slideably positioned within a central passage of the spool. The plunger is configured to engage a plunger stop when the pull-in coil is energized. In at least one embodiment, the hold-in coil is separated from the plunger stop in the axial direction and the hold-in coil encircles the plunger stop.
