Starting System Circuit Description

Moving the ignition switch to the CRANK position sends a 12 V signal to the park neutral switch on the transmission (or clutch switch). When the park neutral switch is in the PARK or NEUTRAL position (or the clutch switch is closed), it completes the B+ voltage circuit to the starter solenoid S terminal.
