ELECTRICAL SYSTEM
BATTERY
The battery is rated at 12 V, 540 ccA. The battery
is located in the engine compartment. When
removing battery cables, remove the negative (--)
cable before the positive (+) cable.
Do not allow the battery to remain in discharged
condition for any length of time. Do not operate
the machine if the battery is in poor condition or
only 25% of the charge is left.
Clean the top surface and the terminals of the
battery periodically. Use a strong solution of
baking soda and water. Brush the solution
sparingly over the battery top, terminals, and
cable clamps. Do not allow any baking soda
solution to enter the battery. Use a wire brush to
clean the terminal posts and the cable
connectors. After cleaning, apply a coating of
clear petroleum jelly to the terminals and the
cable connectors. Keep the top of the battery
clean and dry.
Keep all metallic objects off the top of the battery,
as they may cause a short circuit. Replace worn
or damaged wires.
The electrolyte level in regular non--sealed
batteries can be checked. The level must always
be above the battery plates. Add distilled water to
maintain solution at the correct level above the
plates, but do not overfill. Never add acid to
batteries, only water. Keep vent plugs firmly in
place at all times, except when adding water or
taking hydrometer readings.
FOR SAFETY: When Servicing Machine,
Avoid Contact With Battery Acid.
If, when checking battery specific gravity, one or
more battery cells tests lower than the other
battery cells (0.050 or more), the cell is damaged,
shorted, or is about to fail.
NOTE: Do not take readings immediately after
adding water -- if the water and acid are not
thoroughly mixed, the readings may not be
accurate. Check the hydrometer readings against
this chart:
SPECIFIC GRAVITY
BATTERY
at 80_ F(27_ C) CONDITION
1.260 -- 1.280 100% charged
1.230 -- 1.250 75% charged
1.200 -- 1.220 50% charged
1.170 -- 1.190 25% charged
1.110 -- 1.160 Discharged
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80_ F
(27_ C), the reading must be temperature
corrected.
To determine the corrected specific gravity
reading when the temperature of the battery
electrolyte is other than 80_ F(27_ C):
Add to the specific gravity reading 0.004, 4
points, for each 10_ F(5.5_ C) above
80_ F(27_ C).
Subtract from the specific gravity reading
0.004, 4 points, for each 10_ F(5.5_ C)
below 80_ F(27_ C).
