OPERATION
When engine is stoppedWhen the ignition switch is switched to the “ON”
position, electricity flows from the
‘I” terminal of
the generator to the field coil, and at the same time
the charging warning light illuminates.
When engine is being started/has started
When the engine is started, charging voltage is ap-
plied to the ‘I” terminal of the generator, with the
result that the charging warning light is extinguished.
In addition, because battery voltage is applied to
the “S” terminal of the generator, this battery voltage
is monitored at the
IC voltage regulator, thus switch-ing ON and OFF the current to the field coil and
thereby controlling the output voltage of the genera-
tor.
Power is supplied to each load from the “B” terminal
of the generator.
NOTE
The generator relay functions as a back-up for the
flow of electricity to the field coil if there is a discon-
nection or damaged wiring of the charging warning
light.

1 Generator relayI A I
TROUBLESHOOTING HINTS1. Charging warning light does not go on when
the ignition switch is turned to “ON”, before the
engine starts.l Check the bulb.
2.Charging warning light fails to go off once the
engine starts.l
Check the IC voltage regulator (located with-
in the generator).
3. Discharged or overcharged battery.l
Check the IC voltage regulator (located with-
in the generator).4. The charging warning light illuminates dimly.
l Check the diode (within the combination
meter) for a short-circuit.

OPERATION
L
0For models equipped with the M/T, the clutch
pedal position switch contact is switched OFF
when the clutch pedal is depressed; when the
ignition switch is then switched to the “ST’ posi-tion, electricity flows to the starter relay and
the starter motor, the contact (magnetic switch)of the starter is switched ON and the starter
motor is activated.
NOTEIf the ignition switch is switched to the “ST
position without the clutch pedal being de-
pressed, electricity flows to the starter relay
(coil), the clutch pedal position switch (contacts)
and to ground, with the result that the contacts
of the starter relay are switched OFF, and, be-
cause the power to the starter motor is thereby
interrupted, the starter motor is not activated.lFor models equipped with the
AIT, when the
ignition switch is switched to the “ST’ position
while the selector lever is at the “P” or “N” posi-
tion, the contact (magnetic switch) of the starter
is switched ON and the starter motor is activated.
TROUBLESHOOTING HINTSThe starter motor does not operate at all.
l Check the starter (coil).
lCheck for poor contact at the battery terminals
and starter.l Check Park/Neutral position switch.
l Check clutch pedal position switch.
l Check starter relay.
l Check theft-alarm starter relay.
l Check key reminder switch.

Refer to GROUP 22
- Manual Transaxle, or GROUP 23 -
Automatic Transaxle.INSPECTION
PINION GAP ADJUSTMENT(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2)Connect a 12 V battery between S-terminal and M-terminal.(3) Set switch to “ON”, and pinion will move out.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.(4) Check pinion to stopper clearance (pinion gap) with a
feeler gauge.
Standard value: 0.5-2.0 mm (.020-,079 in.)

MAGNETIC SWITCH PULL-IN TEST(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2)
Connect a 12 V battery between S-terminal and M-terminal.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.
(3) If pinion moves out, then pull-in coil is good. If it doesn’t,
replace magnetic switch.
MAGNETIC SWITCH HOLD-IN TEST(1) Disconnect field coil wire from M-terminal of magnetic
switch.(2) Connect a 12 V battery between S-terminal and body.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.(3) Pull out the pinion by hand until it comes into contact
with the pinion stopper.
(4)If pinion remains out, everything is in order. If pinion moves
in, hold-in circuit is open. Replace magnetic switch.
FREE RUNNING TEST
(1) Place starter motor in a vise equipped with soft jaws andconnect a fully-charged
12-volt battery to starter motor
as follows:
(2) Connect a test ammeter (loo-ampere scale) and carbon
pile rheostat in series with battery positive post and starter
motor terminal.
(3) Connect a voltmeter (15volt scale) across starter motor.
(4) Rotate carbon pile to full-resistance position.
(5)Connect battery cable from battery negative post to starter
motor body.(6) Adjust rheostat until the battery voltage shown by the
voltmeter is 11 V.
(7) Confirm that the maximum amperage is within the specifi-
cations and that the starter motor turns smoothly and freely.
Current: Max. 90 Amps

(1) Press the stop ring, by using an appropriate socket,wrench, to the snap ring side.
(2)After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the overrunning clutch.STARTER MOTOR PARTS CLEANING
1.Do not immerse parts in cleaning solvent. Immersing the
yoke and field coil assembly and/or armature will damage
insulation. Wipe these parts with a cloth only.
2.Do not immerse drive unit in cleaning solvent. Overrunning
clutch is pre-lubricated at the factory and solvent will wash
lubrication from clutch.3. The drive unit may be cleaned with a brush moistened
with cleaning solvent and wiped dry with a cloth.
