rod.
2) Disconnect the positive (+) terminal after dis-
connecting the negative (−) terminal of battery.
3) Remove flange nuts from battery rods and take
off battery holder.
4) Remove battery.

C: INSPECTION
WARNING:
¼ Electrolyte has toxicity; be careful handling
the fluid.
¼ Avoid contact with skin, eyes or clothing.
Especially at contact with eyes, flush with
water for 15 minutes and get prompt medical
attention.
¼ Batteries produce explosive gases. Keep
sparks, flame, cigarettes away.
¼ Ventilate when charging or using in enclosed
space.
¼ For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a
battery.
¼ Do not let battery fluid contact eyes, skin,
fabrics, or paint-work because battery fluid is
corrosive acid.
¼ To lessen the risk of sparks, remove rings,
metal watch-bands, and other metal jewelry.
Never allow metal tools to contact the positive
battery terminal and anything connected to it
while you are at the same time in contact with
any other metallic portion of the vehicle
because a short circuit will be caused.
1. EXTERNAL PARTS:
Check for the existence of dirt or cracks on the
battery case, top cover, vent plugs, and terminal
posts. If necessary, clean with water and wipe with
a dry cloth.
Apply a thin coat of grease on the terminal posts
to prevent corrosion.
2. ELECTROLYTE LEVEL:
Check the electrolyte level in each cell. If the level
is below MIN LEVEL, bring the level to MAX
LEVEL by pouring distilled water into the battery
cell. Do not fill beyond MAX LEVEL.
3. SPECIFIC GRAVITY OF
ELECTROLYTE:
S149011A1003
1) Measure specific gravity of electrolyte using a
hydrometer and a thermometer.
Specific gravity varies with temperature of electro-
lyte so that it must be corrected at 20°C (68°F)
using the following equation:
