57.8 ELECTRICAL SYSTEM
Electrical schematics are attached at the back of
this manual.
57.8.1 Battery
WARNING
• Gas given off by
battery electrolyte
is explosive. Keep
all smoking
materials, sparks
and flames away
from batteries.
• Follow proper charging and boosting
procedures given in this section.
• Ventilate when charging in enclosed
space.
• Always wear protective eye-wear when
working near batteries.
• Do not tip batteries more than 45 to
avoid electrolyte loss.
• Battery electrolyte causes severe burns.
Avoid contact with skin, eyes or clothing.
• Keep batteries out of reach of children.
• If electrolyte is spilled or splashed on
clothing or the body, neutralize it
immediately with a solution of baking
soda and water, then rinse with clean
water.
• Electrolyte splashed into the eyes is
extremely dangerous. Should this occur,
force the eye open and flood with cool,
clean water for five minutes. Call a doctor
immediately.
• To avoid shocks, burns or damage to
electrical system, disconnect battery
ground cable before working in an area
where you might accidentally contact
electrical components.
• Do not operate the engine with alternator
or battery disconnected. With battery
cables disconnected and engine running,
a high voltage can be built up if terminals
touch the frame. Anyone touching the
frame under these conditions would be
severely shocked.
• When working around storage batteries,
remember that all of the exposed metal
parts are "live". Never lay a metal object
across the terminals because a spark or
short circuit will result.
57.8.1.1 Maintenance
CAUTION
Do not attempt to service battery unless you
have the proper equipment and experience
to perform the job. Have it done by a
qualified dealer
a. Check battery charge once a year, more often if
operating in cold weather. Hydrometer readings
should be 1.260 to 1.300. Readings below
1.250 indicate charging is required. See Section
7.10.1.2 Charging. Add electrolyte if necessary.
See Section 7.10.1.4 Adding Electrolyte.
b. Keep battery clean by wiping it with a damp
cloth.
c. Keep all connections clean and tight. Remove
any corrosion and wash terminals with a solution
of baking soda and water. A light coating of
grease on terminals (after cables are attached)
will reduce corrosion.
d. To prolong battery life, store batteries fully
charged and at +20 ° to +80°F (-7° to +26°C).
Check voltage after storage and recharge as
needed, according to battery and charger
manufacturer recommendations.
e. Do not stack batteries on top of each other.
