DESCRIPTION AND OPERATION (Continued)

Downloaded from www.Manualslib.com manuals search engine 8W-21 STARTING SYSTEM
DESCRIPTION AND OPERATION
STARTING SYSTEM- MANUAL TRANSMISSION
The Power Distribution Center (PDC) supplies bat-
tery voltage to the engine starter motor solenoid
through circuit T40 when the coil side of the engine
starter motor relay energizes. Circut A1 supplies the
battery voltage for the contact side of the relay. Cir-
cuit A1 and circuit T40 are protected by a 30 amp
fuse and feeds the contact side of the engine starter
motor relay. Both the 30 amp fuse and the engine
starter motor relay are located in the PDC.
The ignition switch supplies battery voltage to the
coil side of the engine starter motor relay on circuit
A41 when the key is moved to the START position
and the operator has pressed the clutch pedal to
CLOSE the clutch pedal position switch. Circuit Z1
supplies the ground for the coil side of the engine
starter motor relay. When the coil side of the relay
energizes, the contacts CLOSE, supplying battery
voltage to the engine starter motor solenoid.
Circuit A0 (battery positive cable) supplies battery
voltage to the motor of the starter when the solenoid
energizes.
HELPFUL INFORMATION
²Check for blown engine starter motor fuse in the
PDC.
²Move ignition key to the START position and
with the clutch pedal pressed, listen for starter motor
relay to click. The engine starter motor relay is
located in the PDC.
²Check for a good ground at starter motor.
²The left headlamp ground is the end point for
the starter relay coil ground circuit and is located at
the left side of the radiator closure panel.
STARTING SYSTEM (AUTOMATIC TRANSMISSION)
The Power Distribution Center (PDC) supplies bat-
tery voltage to the engine starter motor solenoid
through circuit T40 when the coil side of the engine
starter motor relay energizes. Circuit A1 supplies
battery voltage to the contact side of the relay. Cir-
cuit A1 and circuit T40 are protected by a 30 amp
fuse and feeds the contact side of the engine starter
motor relay. Both the 30 amp fuse and the engine
starter motor relay are located in the PDC.
The ignition switch supplies battery voltage to the
coil side of the engine starter motor relay on circuit
A41 when the key is moved to the START position
and the park/neutral portion of the park/neutral posi-
tion switch (3 speed transmission) is CLOSED.
Ground for the coil side of the engine starter motor
relay is supplied by circuit T41.Circuit A0 (battery positive cable) supplies battery
voltage to the motor of the engine starter when the
solenoid energizes.
HELPFUL INFORMATION
²Check for blown engine starter motor fuse in the
PDC.
²With the gear selector in the Park or Neutral
position, move ignition key to the START position
and listen for engine starter motor relay to click. The
engine starter motor relay is located in the PDC.
²Check for a good ground at engine starter motor.
