Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
sion to the battery racks or surrounding area should be
present. Any corrosion found should be immediately
removed with a putty knife and a wire brush. The area
should be washed with a solution of sodium bicarbonate
(baking soda) and water and thoroughly dried before
priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and
the battery hold downs tightened to 45 - 55 in. lbs. (5 - 6
Nm) torque, to prevent movement but not tight enough to
cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from
the battery terminals or the wire terminals with a solution
of sodium bicarbonate (baking soda) and brush clean if
required.
To prevent battery
explosion that could
result in severe per-
sonal injury or death, extreme care must be
used with aerosol containers of battery ter-
minal protectant. Insulate the metal contain-
er to prevent the metal can from contacting
battery terminals which could result in an
explosion.
Use care to connect the battery wires as shown (Ref Fig.
5 on page H-4). Ensure that all battery terminals are
installed crimp up. Tighten the battery post hardware to
50 - 70 in. lbs. (6 - 8 Nm) torque
. Protect the battery ter-
minals and battery wire terminals with a commercially
available protective coating.
Prolonged Storage
Battery charger and controller
and other electronic devices
need to be disconnected since they will contribute to
the premature discharge of batteries.
During periods of storage, the batteries will need atten-
tion to keep them maintained and prevent discharge.
In high temperatures the chemical reaction is faster,
while low temperatures cause the chemical reaction to
slow down. A vehicle that is stored at 90 F (32 C) will
lose .002 of specific gravity each day. If a fully charged
battery has a specific gravity of 1.275, and the battery is
allowed to sit unused, it will become partially discharged.
When it reaches 1.240, which it will do in less than
twenty days, it should be recharged. If a battery is left in
a discharged state, sulfating takes place on and within
the plates. This condition is not reversible and will cause
permanent damage to the battery. In order to prevent
damage, the battery should be recharged. A hydrometer
(P/N 50900-G1) can be used to determine the specific
gravity and therefore the state of charge of a battery.
In winter conditions, the battery must be fully charged to
prevent the possibility of freezing (Ref Fig. 6 on page H-
5). A fully charged battery will not freeze in temperatures
above -75 F (-60 C). Although the chemical reaction
is slowed in cold temperatures, the battery must be
stored fully charged, and disconnected from any circuit
that could discharge the battery. For portable chargers,
disconnect the charging plug from the vehicle receptacle.
For on-board chargers, disconnect the charging harness
from the batteries. The batteries must be cleaned and all
deposits neutralized and removed from the battery case
to prevent self discharge. The batteries should be tested
or recharged at thirty day minimum intervals.
