MAGNETIC SWITCH HOLD-IN TEST
1. Disconnect the field coil wire from the M-terminal of the
magnetic switch.
This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the S-terminal and body.
3. Manually pull out the pinion as far as the pinion stopper
position.
4. If the pinion remains out, everything is operating properly. If
the pinion moves in, the hold-in circuit is open. Replace the
magnetic switch.
.
FREE RUNNING TEST
1. Place the starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to the starter motor
as follows:
2. Connect a test ammeter (100-ampere scale) and carbon pile
rheostat in series between the positive battery terminal and
starter motor terminal.
3. Connect a voltmeter (15-volt scale) across the starter motor.
4. Rotate the rheostat to full-resistance position.
5. Connect the battery cable from the negative battery terminal
to the starter motor body.
6. Adjust the rheostat until the battery positive voltage shown
on the voltmeter is 11 V.
7. Confirm that the maximum amperage is within the
specifications and that the starter motor turns smoothly and
freely.
Current: maximum 95 Amps
.
MAGNETIC SWITCH RETURN TEST
1. Disconnect the field coil wire from the M-terminal of the
magnetic switch.
This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the M-terminal and body.
Be careful not to get your fingers caught when pulling
out the pinion.
3. Pull the pinion out and release. If the pinion quickly returns
to its original position, everything is operating properly. If it
doesn't, replace the magnetic switch.

<> SNAP RING AND STOP RING REMOVAL
1. Press a long socket wrench of appropriate size to the stop
ring. Then tap the socket wrench to remove the stop ring to
the pinion gear side.
2. After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the overrunning clutch.
STARTER MOTOR PART 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 shop towel only.
2. Do not immerse the drive unit in cleaning solvent.
Overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from the clutch.
3. The drive unit may be cleaned with a brush moistened with
cleaning solvent and wiped dry with a shop towel.

INSPECTIONM1162001300102.
COMMUTATOR CHECK
1. Place the armature on a pair of V-blocks, and check the
deflection by using a dial gauge.
Standard value: 0.05 mm (0.002 inch)
Limit: 0.1 mm (0.004 inch)
2. Check the outer diameter of the commutator.
Standard value: 29.4 mm (1.16 inches)
Minimum limit: 28.8 mm (1.13 inches)
3. Check the depth of the undercut between segments.
Standard value: 0.5 mm (0.02 inch)
Minimum limit: 0.2 mm (0.008 inch)
.
BRUSH CHECK
1. Check the brush for roughness of the surface that contacts
the commutator and check the brush length. Replace the
brush holder if this measurement exceeds the limit.
Minimum limit:
7.0 mm (0.28 inch)
2. If the contacting surface has been corrected or the brush
has been replaced, correct the contacting surface by
winding sandpaper around the commutator.
.

STARTING SYSTEM
ENGINE ELECTRICAL16-29
OVERRUNNING CLUTCH CHECK
1. While holding the clutch housing, rotate the pinion. The drive
pinion should rotate smoothly in one direction, but should
not rotate in the opposite direction. If the clutch does not
function properly, replace the overrunning clutch assembly.
2. Inspect the pinion for wear or burrs. If the pinion is worn or
burred, replace the overrunning clutch assembly. If the
pinion is damaged, also inspect the ring gear for wear or
burrs.
.
FRONT AND REAR BRACKET BUSHING CHECK
Inspect the bushing for wear or burrs. If the bushing is worn or
burred, replace the front bracket assembly or rear bracket
assembly.
.
ARMATURE CHECK
1. Check that the armature coil is not grounded.
2. Place the armature in a growler.
3. Hold a thin steel blade parallel and just above while rotating
the armature slowly in the growler. A shorted armature will
cause a blade to vibrate and be attracted to the core.
Replace the shorted armature.
4. Check the insulation between the armature coil cores and
the commutator segments. They are normal if there is no
continuity.
5. Check for continuity between the segments. The condition is
normal if there is continuity.

the power windows operate properly. If they don't, then
troubleshoot as described in GROUP 54B, SWS Diagnosis
P.54B-57.
2. Turn ON the power window lock switch of the power window
main switch. Then operate the passenger's door and rear
door power window sub-switches to ensure that they do not
operate. If they do, replace the power window main switch
(Refer to P.42-39).

the unlock side to unlock the driver's door and fuel lid door.
Turn the key once again to the unlock side to unlock all
doors and fuel lid door.
All doors and fuel lid door can be locked using the door lock
switch built into the front power window (main or sub )
switch.

BASIC BRAKE SYSTEM DIAGNOSIS
BASIC BRAKE SYSTEM35A-4
STEP 2. Check disc brake pistons for smooth
operation.
(1) With engine not running, depress the brake pedal
rapidly several times to deplete booster vacuum
reserves.
(2) Test each disc brake assembly one at a time.
a. Remove the lower caliper bolt, then remove
caliper from mount.
b. Have an assistant slowly depress the brake
pedal. Confirm piston(s) extend slowly and
smoothly with no jumpiness. Repeat for each
disc brake assembly.
Q: Do (does) the piston(s) move correctly?
YES :
Go to Step 3.

brake pedal, depress the pedal firmly and
measure the distance the pedal traveled.
Q: Is the distance greater than 20 mm (0.8 inch)?
YES :
Bleed the brakes to remove air in the fluid
(Refer to P.35A-16). Then go to Step 7.
NO : Go to Step 3.
STEP 3. Check the brake booster function.
Refer to P.35A-14.
