Check for Wear and Damage

The starter should crank the engine smoothly and steadily.

If the starter engages, but cranks the engine erratically,

remove it, and inspect the starter drive gear and torque

converter ring gear for damage.

Check the drive gear overrunning clutch for binding or

slipping when the armature is rotated with the drive

gear held. If the clutch is damaged, replace the clutch

assembly.

Check Cranking Voltage and Current Draw

Cranking voltage should be no less than 8.5 volts.

Current draw should be no more than 380 amperes.

If cranking voltage is too low, or current draw too high,

check for:

Dead or low battery

Open circuit in starter armature commutator segments

Starter armature dragging

Shorted armature winding

Excessive drag in engine

Check Cranking rpm

Engine speed during cranking should be above 100 rpm.

If speed is too low, check for:

Loose battery or starter terminals

Excessively worn starter brushes

Open circuit in commutator segments

Dirty or damaged helical spline or drive gear

Defective drive gear overrunning clutch

Check Starter Disengagement

With the shift lever in turn the ignition switch to

"START (III)", and release to "ON (II)". The starter drive

gear should disengage from the drive plate/ring gear

when you release the key.

If the drive gear hangs up on the drive plate/ring gear,

check for:

• Solenoid plunger and switch malfunction

• Dirty drive gear assembly or damaged overrunning

Cruise Control

Description (cont'd)

The electrically operated actuator controls the throttle position in the same way as a vacuum operated actuator. The mag-

netic clutch is part of the safety system and controls acceleration and deceleration.

OUTPUT LINK

MOTOR

To ACCELERATOR PEDAL

DECELERATION

ACCELERATION

ACTUATOR CABLE

Acceleration

Due to the rotation of the motor output shaft, power is transmitted to the magnetic clutch by the transmission gear and

the worm wheel. The magnetic clutch is rotated and magnetized. It attracts the clutch plate and power is transmitted to the

output link by the gear directly connected to the clutch plate and the output gear. The output link rotates clockwise, then

the actuator cable opens the throttle, and the car accelerates.

Deceleration

The motor output shaft rotates in reverse direction of acceleration, then, in the same way, the power is transmitted to the

output link. The output link rotates counterclockwise, then the actuator cable closes the throttle, and the car decelerates.
