Battery Service
The battery is the heart of the electrical system. With
regular and proper service, battery life can be extended.
Additionally, battery and electrical component failure
can be prevented.
WARNING
POTENTIAL HAZARD:
Either the battery terminals or metal tools could
short against metal vehicle components.
WHAT CAN HAPPEN:
Sparks can cause the battery gasses to explode.
Damaged cables could short against metal ve-
hicle components and cause sparks.
HOW TO AVOID THE HAZARD:
When removing or installing the battery, do not
allow the battery terminals to touch any metal
parts of the vehicle.
Always DISCONNECT the negative (black) bat-
tery cable before disconnecting the positive
(red) cable.
Always RECONNECT the positive (red) battery
cable before reconnecting the negative
(black) cable.
Do not allow metal tools to short between the
battery terminals and metal parts of the ve-
hicle.
Always keep the battery strap in place to protect
and secure the battery.

Removal (Fig. 28)
IMPORTANT: Be careful not to damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Position vehicle on a level surface, set parking
brake, turn ignition off, and remove key.
2. Raise bed and secure with prop rod. Unhook battery
strap.
3. Disconnect negative (black) cable first to prevent
short circuiting the battery, other components, or opera-
tor’s hands. Disconnect positive (red) cable.

4. Make sure that filler caps are on tightly.
5. Remove battery from chassis to a service area. This
will minimize possible battery damage and allow better
access for inspection and service.
WARNING
POTENTIAL HAZARD:
Battery electrolyte contains sulfuric acid which is
a deadly poison and it causes severe burns.
WHAT CAN HAPPEN:
If you carelessly drink electrolyte you could die
or if it gets onto your skin you will be burned.
HOW TO AVOID THE HAZARD:
Do not drink electrolyte and avoid contact with
skin, eyes or clothing. Wear safety glasses to
shield your eyes and rubber gloves to protect
your hands.
Fill the battery where clean water is always avail-
able for flushing the skin. Always RECONNECT
the positive (red) battery cable before recon-
necting the negative (black) cable.
Follow all instructions and comply with all safety
messages on the electrolyte container.
Inspection, Maintenance, and Testing
1. Perform the following inspections and maintenance:
A. Check for cracks caused by overly tight or loose
hold–down clamp. Replace battery if cracked and
leaking.
B. Check battery terminal posts for corrosion. Use a
terminal brush or steel wool to clean corrosion from
the battery terminal posts.
