ELECTRICAL SYSTEM
The electrical system is a 12-volt negative ground
system. The battery is located on the right side of the
operator’s platform behind the disconnect switch.
Battery Servicing
Batteries contain sulfuric acid that
produces explosive gases. DO NOT allow ames or
sparks near the battery as serious injury can result.
Always wear safety goggles and
protective clothing when servicing the battery.
In case of acid contact with skin or eyes, ush
immediately with water for a minimum of 15 minutes
and get prompt medical attention.
When servicing batteries, ALWAYS
disconnect the negative (-) (ground) cable rst and
connect it last. Generally, if the negative cable is
grounded during removal, sparks will not occur.
If the positive cable is grounded during removal,
sparks will occur and could ignite explosive gases.
NOTE: The electrical system is a negative ground
system. Connect the positive (+) cable to the
positive (+) post of both batteries. Connect
the ground (-) cable to the negative (-) post of
both batteries.
NOTE: When replacing the batteries, discard the old
batteries properly.
Be sure the terminals and battery posts are thoroughly
cleaned and that battery cable terminals are tight.
Dirty or loose connections can create high electrical
resistance and permit arcing.
Keep the battery clean by washing it off whenever dirt
build-up is excessive. If corrosion is present around
terminal connections, remove them and wash with an
ammonia solution or a solution consisting of 1/4 pound
(0.11 kg) baking soda and 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.
When batteries are connected, follow these rules:
1. Disconnect negative (-) battery cable when working
on or near the alternator.
2. DO NOT attempt to polarize alternator.
3. Make sure alternator wires are correctly connected
before connecting battery terminals.
4. DO NOT ground alternator output terminal.
5. DO NOT disconnect or connect alternator wires
while batteries are connected or while alternator is
operating.
6. Connect batteries or booster battery in the correct
polarity [positive (+) to positive (+), negative (-) to
negative (-)].
7. DO NOT disconnect batteries when engine is
running and alternator is charging.
8. Disconnect battery cables before connecting
battery charger to batteries. Charge batteries
separately.
Battery Maintenance
Perform maintenance on the battery as follows:
1. Disconnect battery clamps, disconnecting the black
(grounded) clamp rst.

2. Clean terminals with a stiff brush or battery service
tool. (Figure 5-6)
3. Apply grease at the base of the battery terminals to
prevent gas from escaping.
4. Install and tighten battery clamps, connecting the
black (grounded) clamp last.
