Battery voltage is available at the Ignition Switch and the Starter Relay contacts at all times through the RED (242) wire from the IGN-A fuse in the Underhood Fuse-Relay Center. Placing the Ignition Switch in START closes contacts to apply voltage on the YEL (5) wire to the Park/Neutral Position Switch. If the Automatic Transmission is in either Park or Neutral, voltage is applied from the YEL (1737) wire to the Starter Relay coil. The Starter Relay coil is grounded at Ground G103 by the BLK (150) wire. With voltage applied to the coil, the Starter Relay energizes. Voltage is then applied to the Starter Solenoid Winding Terminal S through the PPL (6) wire. Battery voltage is also available at all times through the BLK (1) wire at Starter Solenoid Terminal B. With battery voltage applied at Starter Solenoid Terminal S, current flows though the Hold-In Winding to the mechanical ground at the solenoid. Simultaneously, current flows through the Pull-In Winding and the Starter Motor to the Starter Motor's mechanical ground. The combined force of these windings overcomes the force of the Return Spring and pulls the starter's Plunger to engage the starter with the Flywheel Drive Assembly though the Shift Lever. The engine starts to turn over. The Plunger actuation also operates a contact in the Starter Solenoid which closes to apply battery voltage directly to the Starter Motor. With battery voltage applied directly to the Starter Motor, the Pull-In Winding no longer has a voltage drop across the coil and current ceases to flow. The Starter Solenoid remains engaged due to the current flow through the Hold-In Winding alone. The Starter motor continues to operate until the Ignition Switch is returned to the RUN position. With the Ignition Switch now in the RUN position, voltage is removed from Starter Solenoid Terminal S. However, voltage is still present at Terminal B. Both the Hold-In Winding and the Pull-In Winding are energized by battery voltage from the BLK (1) wire. However, the forces from these windings now oppose one another and the Plunger returns to the disengaged position through the operation of the Return Spring. This operates the contact to remove battery voltage from the Starter Motor and the motor stops. Both windings also de-energize. This Plunger operation also retracts the starter from the Flywheel Drive Assembly and the engine operates on its own power.

The Generator provides voltage to operate the vehicle's electrical system and to charge the Battery. The Generator operates as an alternator to generate Alternating Current (AC) electricity which is then rectified to Direct Current (DC) electricity. The Generator is driven by belt and rotates as the engine rotates. An excitation magnetic field is induced in the Generator's rotor by the Regulator. The Generator's rotation causes the excitation field to move through the stator windings. The motion of the field through the stator conductors induces an alternating magnetic field to be generated in the stator. Diodes in the Rectifier Bridge allow stator current to flow as a result of this alternating magnetic field but only in the one direction which would charge the battery. The Generator's internal solid state voltage Regulator regulates the pulse width of the excitation field so as to regulate the voltage generated at the BAT Terminal to be 14 volts, nominally. The excitation field is present in the Generator only when the Ignition Switch is in RUN or START. The Generator does not contain permanent magnetism of sufficient strength to produce a usable excitation magnetic field. The Generator's Turn On Input is present from the BRN (25) wire which connects the Generator to the Instrument Cluster. Voltage is present to the Instrument Cluster from GAUGES fuse 4 on the PNK (39) wire. The Battery indicating lamp is only illuminated when there is sufficient current flow to cause the lamp filament to emit light. The slight current flow used by the Generator in normal operations is allowed by the resistor which bypasses the indicatorlamp. Thus, an open filament in the lamp will not prevent generator operations. The Generator controls the Battery indicating lamp in the Instrument Cluster. Internal logic at the Generator closes an internal contact to ground the indicator lamp circuit's BRN (25) wire when the Generator output voltage is either too high or too low. The indicator lamp circuit is only powered when the Ignition Switch is in the RUN and START position.
