4.7 BATTERY
4.7.1. BATTERY REMOVAL
1. Remove battery retainer.
2. Slide battery from battery box to gain
access to terminal cables.
3. Observe and note cable positions on
battery. See Figure 4.9.
4. Disconnect cables from battery terminals,
disconnecting BLACK (Negative) cable first,
then disconnect RED (Positive) last.
Retain
mounting bolts and nuts.

CAUTION
The electrolyte (acid) produces a highly explosive gas.
Keep all sparks, flame and fire away from area when
charging battery or when handling electrolyte or
battery. Electrolyte (acid) is a highly corrosive liquid.
Wear eye protection. Wash affected areas immediately
after having eye or skin contact with electrolyte (acid).
Battery acid is corrosive. Rinse empty acid containers
with water and mutilate before discarding. If acid is
spilled on battery, bench, or clothing, etc., Flush with
clear water and neutralize with baking soda.
4.7.3. BATTERY SERVICE
1. Remove battery.
2. Place battery in a well ventilated area
on a level surface.
3. Using distilled water, refill cells as
required to cover cell plates of which can
also be seen through the plastic battery
case.
4. With cell caps removed, connect battery
changer to battery terminals. RED to positive
(+) terminal and BLACK to negative (-)
terminal.
5. Slow charge battery at 1 amp for 10
hours. An alternative fast charge should be
no more than 2.5 for four hours.
6. If battery will not accept charge or is
partially charged after 10 hours of charging
at 1 amp, replace with new battery.
CAUTION
Cables must be connected to battery terminals in
the proper position. RED (Positive) cable must go to
the ( + ) terminal. BLACK (Negative) cable must go
to the ( -) terminal.
4.7.2. BATTERY INSTALLATION
1. Slide
battery
partially
into
battery
compartment.
2. Connect cables to battery terminals.
Connect
RED
(Positive)
cable
first.
Connect BLACK (Negative) cable last.
3. Reinstall battery retainer.
4.7.4. BATTERY TESTING
There are two types of battery tests:
Unloaded and Loaded. The unloaded test
is the procedure that will be discussed. It's
the simplest and most commonly used. An
unloaded test is made on a battery without
discharging current. To perform unloaded
testing, check charge condition using either
a hydrometer or voltmeter.
1. Using a voltmeter, voltage readings
appear instantly to show the state of
charge. Remember to hook the positive
lead to the battery's positive terminal, and
the negative lead to the negative terminal.
2. A hydrometer measures the specific
gravity of each cell. The specific gravity
tells the degree of charge; generally, a
specific gravity of about 1.265 to 1.280
indicates full charge. A reading of 1.230 to
1.260 indicates the battery should be
charged before testing. The chart on the
next page shows the charge level as
measured by syringe float hydrometer,
digital voltmeter and five ball hydrometer.
