TEST
NOTICE:
These tests must be done within 3 to 5 seconds to avoid the
coil to be burned ± out.
1. DO PULL±IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as shown.
Check that the pinion gear moves outward.
2. DO HOLDING TEST
While connected as above with the pinion gear out, disconnect
the negative (±) lead from terminal C. Check that the pinion gear
remains out.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (±) lead from the starter body. Check
that the pinion gear returns inward.
4. DO NO±LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as shown.
(b) Check that the starter rotates smoothly and steadily with
the pinion gear moving out. Check that the ammeter
shows the specified current.
Specified current:
At 11.5 V: 100 A or less

CHARGING SYSTEM
ON±VEHICLE INSPECTION
CAUTION:

Check that the battery cables are connected to the
correct terminals.

Disconnect the battery cables when the battery is giv-
en a quick charge.

Do not perform tests with a high voltage insulation re-
sistance tester.

Never disconnect the battery while the engine is run-
ning.
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible) and check the charging system.
2. Except Maintenance±Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 to 1.29 at 20°C (68°F)
If the specific gravity is less than the specification, charge the
battery.
3. Maintenance±Free Battery:
CHECK BATTERY VOLTAGE
(a) In the case that 20 minutes have not passe4d after stop-
ping the engine, turn on the ignition switch and the electri-
cal system (headlight, blower motor, rear defogger, etc.)
for 60 seconds before removing the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
