ELECTRICAL SYSTEM
Battery Servicing
The chip spreader electrical system is a 12-volt negative
ground system. Two batteries are located on the left
side of the machine in a battery compartment directly
below the engine access panel. (Figure 5-23)
Figure 5-23. Batteries
NOTE: The electrical system is a negative ground
system. Connect the positive (+) cable to
the positive (+) post of the battery. Connect
the ground cable to the negative (-) post of
the battery. It is advisable to disconnect the
negative (-) cable rst and reconnect it last.
Reversed polarity can damage the electrical
system.
Clean terminals and battery posts thoroughly and check
that battery cable terminals are tight. Dirty or loose
connections can create high electrical resistance and
permit arcing, which will quickly burn and pit terminals
and posts.
Keep the battery clean by washing it off whenever dirt
buildup is excessive. If corrosion is present around
terminal connections, remove them and wash with
ammonia solution or a solution consisting of 1/4 lb. (11 kg)
baking soda added to one quart of warm water. Make
certain the vent caps are tight to prevent solution from
entering the cells. After cleaning, pour clean water over
the battery and surrounding area to wash the solution
away. Check vent cap breather openings to make sure
they are open.
Batteries contain sulfuric acid and
normally produce explosive gases that can cause
serious injury. DO NOT allow ames or sparks to
come near the battery.
When charging or working near a
battery, always shield your face and protect your
eyes. In case of acid contact with skin or eyes,
ush immediately with water for a minimum of 15
minutes and get prompt medical attention. If acid is
swallowed, call a physician immediately.
When replacing the battery, discard the old battery
properly. Before connecting the battery, be sure the
Master Disconnect switch is turned off. The switch
is located on the conveyor control panel left of the
operator. (Figure 5-24)
When servicing the electrical system
or welding on the machine, always turn the Master
Disconnect switch to the OFF position to disconnect
the ground strap from the battery to prevent damage
to the machine electrical system.

Be sure to keep the battery fully charged during cold
weather to keep it from freezing. Freezing weather has
little effect on a fully charged battery.
When connecting a booster battery, if necessary for
cold weather starting, connect one end of the rst
jumper cable to the positive (+) terminal of the dead
battery and the other end to the positive (+) terminal of
the booster battery. Connect one end of the second
jumper cable to the negative (-) terminal of the booster
battery and the other end to the frame of the machine
with the dead battery.
DO NOT attach the negative (-) cable
from the booster battery to the negative (-) post of
the dead battery because a spark could cause an
explosion.
