INSPECTION
1. INSPECT STARTER ASSEMBLY
CAUTION:
As a large electric current passes through the cable during this inspection, a think cable must be used.
If not, the cable may became hot and cause injury.
NOTICE:
(1) Remove the nut, and then disconnect the field coil lead wire
from terminal C.
(2) Connect the battery to the magnet starter switch as shown in
the illustration. Then check that the clutch pinion gear moves
outward.
If the clutch pinion gear does not move, replace the magnet
starter switch assembly.
(b) Perform a holding test.
(1) When the battery is connected as above with the clutch
pinion gear out, disconnect the negative (-) lead from
terminal C. Check that the pinion gear remains out.
If the clutch pinion gear moves inward, replace the magnet
starter switch assembly.

(c) Inspect the clutch pinion gear return.
(1) Disconnect the negative (-) lead from the starter body.
Check that the clutch pinion gear returns inward.
If the clutch pinion gear does not return inward, replace the
magnet starter switch assembly.
(d) Perform an operation test without load.
(1) Connect the field coil lead wire to terminal C.
Torque:
10 N·m {102 kgf·cm, 7ft·lbf}
(2) Mount the starter in a vise between aluminum plates.
(3) Connect the battery and ammeter to the starter as shown in
the illustration.
(4) Check that the starter rotates smoothly and steadily while the pinion gear is moving outward. Then
measure the current.
Standard current:
90 A or less at 11.5 V
If the result is not as specified, replace the starter assembly.
2. INSPECT MAGNET STARTER SWITCH ASSEMBLY
(a) Check the plunger.

(1) Push in the plunger and check that it returns quickly to its
original position.
If the result is not as specified, replace the magnet starter
switch assembly.
(b) Check if the pull-in coil has an open circuit.
(1) Measure the resistance according to the value(s) in the table
below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Terminal 50 - Terminal C
Always
Below 1 Ω
If the result is not as specified, replace the magnet starter
switch assembly.
(c) Check if the holding coil has an open circuit.
(1) Measure the resistance according to the value(s) in the table
below.
Standard Resistance:
TESTER CONNECTION
CONDITION
SPECIFIED CONDITION
Terminal 50 - Switch body
Always
Below 2 Ω
If the result is not as specified, replace the magnet starter
switch assembly.
3. INSPECT STARTER ARMATURE ASSEMBLY
(a) Check the appearance.
If the surface is dirty or burnt, restore the surface with sandpaper (No. 400) or on a lathe.
(b) Measure the resistance.
(1) Measure the resistance according to the value(s) in the table below.
