4.8 BATTERY MAINTENANCE AND
BOOSTING
Inspect the batteries on a regular basis for
damage such as a cracked or broken case or
cover which would allow electrolyte loss.
Check the battery cables for tightness and
corrosion. Remove any acid corrosion from
the battery and cables with a baking soda
and water solution. Coat the terminal con-
nections with di-electric grease.
If it is necessary to use a booster battery to
start the engine, BE CAREFUL! Open the
engine access door on the front of the engine
compartment to gain access to the battery
(Fig. 4.8A, 4.8B). If equipped with a boost-
ing lug, open the control access door (Fig.
4.8C).
BOOSTING PROCEDURES
The ignition must be in the OFF position.
The booster battery to be used must be 12
volt. Connect the end of the first cable to the
positive (+) terminal of the booster battery.
Connect the other end of the same cable to
the screener battery positive (+) terminal, or
to the boosting lug. (See Fig 4.8D). Connect
the end of the second cable to the negative
(–) terminal of the booster battery. Connect
the other end of the same cable to a ground.
Keep cables away from moving parts. Start
the engine. After the engine has started, dis-
connect the end of the second cable from the
negative (–) terminal of the booster battery.
Disconnect the other end of the same cable
from the ground. Disconnect the end of the
first cable from the positive (+) terminal of
the booster battery. Disconnect the other end
of the same cable from the screener battery
positive (+) terminal, or boosting lug (See
Fig 4.8D).

WARNING
To prevent personal injury DO NOT
charge a frozen battery because it can
explode. Let the battery warm to 60
°
F
(15.5
°
C) before putting on a charger.
WARNING
Lead-acid batteries contain sulfuric acid
which will damage the eyes or skin on
contact. Always wear goggles to avoid acid in
the eyes. If acid contacts the eyes, wash
immediately with LARGE QUANTITIES
of clean water and get medical attention.
Wear rubber gloves and protective clothing
to keep acid off the skin. If acid contacts the
skin, wash off immediately with clean water.
