INSPECTION
1. INSPECT STARTER ASSY
NOTICE:
These tests must be performed within 3 to 5 seconds to
prevent burnout of the coil.
(a) Perform the pull-in test.
(1) Remove the nut, then disconnect the lead wire from
terminal C.
(2) Connect the battery to the repair service starter kit
as shown in the illustration. Check that the clutch
pinion gear is extended.
If the clutch pinion gear does not move, replace the starter mag-
netic switch.
(b) Perform the hold-in test.
(1) Disconnect the negative (-) lead from terminal C
with the lead wire disconnected from terminal C.
Check that the clutch pinion gear remains ex-
tended.
If the clutch pinion gear returns inward, replace the starter mag-
netic switch.
(c) Check the operation.
(1) Disconnect the negative (-) lead from the switch
body. Check that the clutch pinion gear returns.
If the clutch pinion gear does not return inward, replace the
starter magnetic switch.

(d) Perform the no-load performance test.
(1) Connect the lead wire to terminal C. Make sure that
the lead is not grounded.
Torque: 10 NVm (102 kgfVcm, 7 ftVlbf)
(2) Clamp the starter in a vise.
(3) Connect the battery and an ammeter to the starter
as shown in the illustration.
(4) Check that the starter rotates smoothly and steadily
with the clutch pinion gear extended. Check that the
ammeter reads the specified current.
Specified current: 90 A or less at 11.5 V
If the current is not as specified, replace the starter.
2. INSPECT STARTER RELAY ASSY
(a) Inspect the resistance.
(1) Using an ohmmeter, measure the resistance be-
tween the terminals.
Standard:
Tester ConnectionSpecified Condition
3 - 510 kW or higher
3 - 5Below 1W
(Apply battery voltage to terminals 1 and 2
If the result is not as specified, replace the starter relay.

ON-VEHICLE INSPECTION
1. INSPECT BATTERY (MAINTENANCE- FREE BAT-
TERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
replace the battery.
(b) Check the battery voltage.
(1) If it has been less than 20 minutes since you
stopped driving the vehicle or since the engine was
stopped, turn the ignition switch and electrical sys-
tems (headlight, blower motor, rear defogger etc.)
to the ON position for 60 seconds. This will remove
the surface charge on the battery.
(2) Turn the ignition switch and electrical systems OFF.
(3) Using a voltmeter, measure the battery voltage be-
tween the negative (-) and positive (+) terminals of
the battery.
Standard voltage: 12.5 to 12.9 V at 20C (68F)
If the voltage is less than the specification, charge the battery.
(c) Check the indicator as shown in the illustration.
HINT:

Blue: OK

White: Charging Necessary

Red: Insufficient Water
2. INSPECT BATTERY (EXCEPT MAINTENANCE-FREE
BATTERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
add distilled water.
