2. Disconnect the battery cables when the battery is given a quick charge.
3. Do not do tests with a high voltage insulation resistance testor.
4. Never disconnect the battery while the engine is running.

1. CHECK BATTERY ELECTROYTE LEVEL AND VOLTAGE
(a) Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled
water if possible.). Need to check the charging system.
(b) Measure the battery voltage between the terminals negative
(–) and positive (+) of the battery.
Standard voltage:
At 20 ° C (68 ° F): 12.7–12.9 V
HINT:
• Before measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight,
blower motor, rear defogger etc.) for 60 seconds to
remove the surface charge.
• If the vehicle has been running, wait 5 minutes or more
after the vehicle stops before measuring the battery
voltage.
If the voltage is less than specification, charge the battery.
HINT: Check the indicator as shown in the illustration.
2. CHECK BATTERY TERMINALS AND FUSES
(a) Check that the battery terminals are not loose or corroded.
If the terminals are corroded, clean the terminals.
(b) Check the fuses for continuity.

3. INSPECT DRIVE BELT
HINT: A belt tensioner is used, so checking the belt tension
is not necessary.
(a) Visually check the drive belt for excessive wear, frayed cords,
etc.
If necessary, 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.
• The drive belt tension can be released by turning the
belt tensioner clockwise.
(b) Check the belt tensioner operation.
• Check that the belt tensioner moves downward when
the drive belt is pressed down at the points indicated in
the illustration with approx. 98 N (10 kgf, 22.0 lbf) of
force.
• Check the alignment of the belt tensioner pulley to make
sure the drive belt will not slip off the pulley.
If necessary, replace the belt tensioner.
• Check that the arrow mark on the belt tensioner falls
within area A of the scale.
If it is outside area A, replace the drive belt.
HINT:
• When a new belt is installed, it should lie within area B.
If not, the drive belt is not correct.
• After installing a drive belt, check that it fits properly in
the ribbed grooves.
