Circuit Description

Starting Circuit:

When the ignition switch is released from the START position, the START relay opens and battery voltage is removed from the starter solenoid S terminal. Current flows from the motor contacts through both windings to the ground at the end of the hold-in winding. However, the direction of the current flow through the pull-in winding is now opposite the direction of the current flow when the winding was first energized.

The magnetic fields of the pull-in and hold-in windings now oppose one another. This action of the windings, along with the help of the return spring, causes the starter drive assembly to disengage and the solenoid switch contacts to open simultaneously. As soon as the contacts open, the starter circuit is turned off.

Moving the ignition switch to the CRANK position closes the circuit to both the pull-in and hold-in windings. The transmission range switch or the Clutch Pedal Position (CPP) switch are in series with, and must be closed, in order for voltage reach the starter solenoid S terminal. Moving the ignition switch to the CRANK position also sends a 12 V signal to the PCM.
