CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance–Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). Check the charging system.
Except Maintenance–Free Battery:
If under the lower level, add distilled water.
2.
Except Maintenance–Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25 – 1.29 at 20
°
C (68
°
F)
If the specific gravity is less than specification, charge the bat-
tery.
3.
Maintenance–Free Battery:
CHECK BATTERY VOLTAGE
(a)
After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b)
Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c)
Measure the battery voltage between the negative (–)
and positive (+) terminals of the battery.
Standard voltage:
12.5 – 12.9 V at 20
°
C (68
°
F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4.
CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES

INSPECT DRIVE BELTS
(a)
Visually check the drive belt for excessive wear, frayed
cords etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a drive belt are considered acceptable.
If the drive belt has chunks missing from the ribs, it should be
replaced.
(b)
Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG–20 (95506–00020)
Borroughs No. BT–33–73F
Drive belt tension:
New belt: 175
±
5 lbf
Used belt: 115
±
20 lbf
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
6.
VISUALLY CHECK GENERATOR WIRING AND LIS-
TEN FOR ABNORMAL NOISES
(a)
Check that the wiring is in good condition.
(b)
Check that there is no abnormal noise from the generator
while the engine is running.
7.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
(a)
Warm up the engine and then turn it off.
(b)
Turn off all accessories.
(c)
Turn the ignition switch ”ON”. Check that the discharge
warning light is lit.
(d)
Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the dis-
charge light circuit.
