HARNESS CONNECTOR INSPECTION
CONNECTOR CONTINUITY AND VOLTAGE TESTWhen checking continuity and/or voltage at the waterproof
connectors, follow the steps below to avoid poor connector
contact and/or reduced waterproof performance of connectors.
(1) When checking is performed with the circuit in the stateof continuity, be sure to use the special tool (harness
connector).
Never insert a test bar from the harness side, because
to do so will reduce the waterproof performance and result
in corrosion.
(2) When the connector
JS disconnected for checking the fe-
male pin, the harness for checking the contact pressureof connector pins should be used.
Never force the insertion of a test bar, because to do
so will cause poor contact.(3) When the male pin is to be checked, apply the test bar
against the pin directly.
Care must be taken not to short-circuit the connector pins.
TERMINAL ENGAGEMENT CHECK
When the terminal stopper of connector is out of order, engage-
ment of male and female terminals becomes improper even
when the connector itself is engaged perfectly and the terminal
sometimes slips out to the rear side of connector. Ascertain,
therefore, that each terminal does not come off the connector
by pulling each harness wire.
CONNECTOR TERMINAL ENGAGEMENT AND
DISENGAGEMENTConnectors which are loose shall be rectified by removing
the female terminal from connector housing and raising its
lance to establish a more secure engagement. Removal of
connector terminal used for MFI and 4 A/l control circuit shallbe done in the following manner.
COMPUTER CONNECTOR(1) Insert screwdriver
[1.4 mm (.06 in.) width] as shown in
the figure, disengage front holder and remove it.

REMOVAL
(1) When removing the stator, unsolder stator lead wirefrom the main diode of the rectifier.
(2) When removing the brush holder, unsolder it from
the rectifier.
Caution
(1) When soldering or unsoldering, be careful to
make sure that heat of soldering iron is not
transmitted to diodes for a long period. Finish
soldering or unsoldering in as short a time
as possible.
(2) Be careful that no undue force is exerted to
leads of diodes.REASSEMBLY SERVICE POINT

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.

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.

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.
