(Continued from previous page) C I R C U IT 0 PE RAT1 0 N STARTER

When the Ignition Switch is moved to the START position, battery voltage is applied to the Starter Solenoid. Both solenoid windings are energized. The circuit through the Pull-In Winding is completed to ground through the Starter Motor. The windings work together magnetically to pull in and hold in the Plunger. The Plunger moves the Shift Lever. This action causes the Drive Assembly to rotate as it engages the Flywheel ring gear on the engine. At the same time, the Plunger also closes the solenoid switch contacts in the Starter Sole- noid. Full battery voltage is applied directly to the Starter Motor and it cranks the engine.

As soon as the solenoid switch contacts close, voltage is no longer applied4hrough the Pull-In Winding, since battery voltage is applied to both ends of the windings. The Hold-In Wind- ing remains energized, and its magnetic field is strong enough to hold the Plunger, Shift Lever, and Drive Assembly solenoid switch contacts in place to continue cranking the engine.

When the Ignition Switch is released from the START position, battery voltage is removed from the PPL wire and the junction of the two windings. Voltage is applied from the Motor Contacts through both windings to ground at the end of the Hold-In Winding. However, the voltage applied to the Pull-In Winding is now opposing the voltage applied 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, with the help of the Return Spring, causes t F - Qrive Assembly to disengage and

the solenoid switch contacts to open simul- taneously. As soon as the contacts open, the starter circuit is turned off.

CIRCUIT OPERATION V6 VIN A, V8 VIN Y

CHARGING

The Generator supplies DC voltage to operate the vehicle’s electrical systems and to recharge its Battery. The output of the Gener- ator is controlled by the built-in solid-state Reg- ulator.

When the Ignition Switch is first moved to RUN or BULB TEST, before the Engine is started, a small current flows through the VOLTS Indicator, the Generator Field winding, and the Regulator. This current lights the VOLTS Indicator. It also produces a magnetic field around the field winding. As the engine starts, the rotation of this small field produces a voltage in the Stator. The regulator senses this voltage and takes control of the field current.

AC voltage is generated in three Stator windings in the Generator. This is charged to DC by the Rectifier Bridge. This DC output is applied to the Battery and the car’s circuits at the BAT terminal of the Generator. A separate output voltage is provided by the Diode Trio to the field winding of the Rotor. In this way, some of the output of the Generator is used to supply its field excitation. The field voltage is also applied to the VOLTS Indicator bulb. This causes the bulb to go out after the engine starts and the Generator is operating. With equal voltage at both sides of the bulb, the bulb goes out.

The Regulator is connected to the battery voltage at Terminal A of the Generator. When the Battery is fully charged, its voltage is high. The Regulator then decreases the Generator field excitation. This reduces the output of the Generator to prevent overcharging the Bat- tery. When the Battery has been discharged or is loaded heavily, its voltage is lower. The Reg- ulator senses this and increases the output of the Generator.

C I RC U IT OPE RAT1 ON TURBO VIN 7

CHARGING

The Generator supplies DC voltage to operate the vehicle’s electrical systems and to charge its Battery. The output of the Generator is controlled by the built-in digital Regulator.

The digital Regulator directly controls the field with a Pulse Width Modulated (PWM) signal, which is valued in duty cycles. When the Ignition Switch is first turned to RUN, before the engine is started, voltage is applied to the Regulator through the VOLTS Indicator bulb. The Regulator, which is in a field strobe function, applies a small percentage of duty cycle to the field windings to produce a magnetic field. As the Generator RPM increases, the field strobe function is disabled and normal regula- tion occurs.

i /


(Continued from previous page) AC voltage is generated in three Stator Wind- ings in the Generator. This is changed to DC voltage by the Rectifier Bridges. This DC output is applied to the Battery and the vehicle’s circuits at the BAT terminal of the Generator. The battery terminal also supplies voltage to the Regulator for field voltage and voltage monitoring.

The Regulator can detect a fault within the Generator and ground the VOLTS Indicator light through a lamp driver. The indicator will light in full brilliance when there is an under or over voltage conditioning, a broken drive belt, an open or shorted field circuit, or an open Reg- ulator.

CIRCUIT OPERATION The Coolant Fan is electrically operated and

is turned on when the engine coolant becomes hot enough to require cooling.

The Low Speed Coolant Fan is controlled by the Low Speed Coolant Fan Relay. This relay is controlled by the ECM and the Low Speed contact of the N C High Pressure Switch. The High Speed Coolant Fan is controlled by the High Speed Coolant Fan Relay. This Relay is controlled by the Coolant Fan Temperature Switch and the Hi Speed contact of the A/C High Pres- sure Switch. When any one of these compo- nents grounds the coil of one of the relays, that particular fan runs.

On all cars, the Coolant Fan Delay Relay oper- ates the Coolant Fan for a short period of time after the engine is turned off. A Solid State timer relay removes the path to ground for the Coolant Fan Delay Relay coil to turn off the fan. Refer to Section 6E for conditions that will cause the ECM to turn the fan ON or OFF.

TROUBLESHOOTING HINTS Try the following checks before doing the Sys- tem Diagnosis.

1. Check GAGES Fuse by observing the SER- VICE ENGINE SOON Indicator with the Ignition Switch in RUN (engine not running).

2. If the Speedometer does not operate, there is a mechanical problem with the Speedometer cable system. See Section 7 of the Service Manual for procedures.

3. Check that ground G120 is clean and tight. Go to System Diagnosis for diagnostic tests.

Battery see 2 SYSTEM DIAGNOSIS

Do the tests listed for your symptom in the Symptom Table below. Tests follow the Symptom Table.

If all voltages are correct, repairheplace the Vehicle Speed Sensor Buffer circuit.

1. Checkhepair PNWBLK (239) wire for an open (see schematic).

2. Check/repair BLK/WHT (450) wire for an open (see schematic).

3. Checkhepair BRN (437) wire for an open (see schematic). Replace Electronic Con- trol Module if the BRN wire is OK.

4. Checkhepair RED (381) wire for an open (see schematic). Replace Cruise Control Module if the RED wire is OK.

CIRCUIT OPERATION The Vehicle Speed Sensor (VSS) generates a

signal that indicates the speed of the vehicle. This signal is processed by the solid-state Vehi- cle Speed Sensor Buffer to supply inputs to the Electronic Control Module (ECM) and the Cruise Control Module.

The Vehicle Speed Sensor is mounted in the back of the Speedometer. The speedometer cable rotates a disk in the Speedometer. The disk has two reflecting surfaces. Light from an infra-red source in the sensor reflects back to a solid-state detector there. As the speedometer cable turns, pulses of light are returned to the detector and electrical pulses are sent by the sensor to the buffer. The frequency of these pulses depends on the speed of the vehicle. As the speed increases, so does the number of voltage pulses produced each second. There are 2000 pulses for each mile that the car travels.

The Vehicle Speed Sensor Buffer takes the voltage pulses from the sensor, and uses them to close two solid-state switches. Each sensor pulse closes these switches once. The output terminals are switched to ground at a rate that indicates the speed of the vehicle. The output switches in the Vehicle Speed Sensor Buffer are solid-state switches, not mechanical ones. Self- powered test lights or ohmmeters should not be used to test them. Do not measure the resistance at the outputs of the buffer.
