Dirty or Loose Connections: improper
connections may stop the flow of electrical
power to and from the battery.
Battery Charging
WARNING
Batteries can injure you severely. They
contain acid, produce poisonous and
explosive gases, and supply levels of
electric current high enough to cause
burns. A spark or flame near a battery
on charge may cause it to explode
with great force. Never remove or tam-
per with the battery caps. Failure to
comply may result in death, personal
injury, equipment or property damage.
Except for using small trickle charges to
maintain battery condition, you should
have your vehicle's batteries charged by a
qualified service facility. To help reduce the
risk of personal injuries, follow these
guidelines carefully when recharging a
battery:
• Before attempting any service in
the electrical installation,
disconnect the battery negative
cable.
• Allow no sparks or open flame
anywhere near the charging area.
• Charge a battery only in a well-
ventilated area, such as outdoors
or in a fully open garage which
contains no pilot lights or other
flames. Gases generated during
the charging process must be
allowed to escape.
• Always make sure the battery
charger is OFF before connecting
or disconnecting the cable clamps.
• To avoid short circuits, damage to
the vehicle, or personal injury,
never place metal tools or jumper
cables on the battery or nearby.
Metal that accidentally comes in
contact with the positive battery
terminal or any other metal on the
vehicle (that is in contact with the
positive terminal), could cause a
short circuit or an explosion.
Charging Reminders
• Use protective eyewear.
• Keep all batteries away from
children.
• Never reverse battery poles.
• Never attempt to place the vehicle
in motion, or run the engine with
batteries disconnected.
• Keep the battery clean and dry.
• Look for any signs of damage.
• Battery terminals should not be
coated with improper grease. Use
petroleum jelly or commercially
available, noncorrosive,
nonconductive terminal coatings.
• Never use a fast charger as a
booster to start the engine. This
can seriously damage sensitive
electronic components such as
relays, radio, etc., as well as the
battery charger. Fast charging a
battery is dangerous and should
only be attempted by a competent
mechanic with the proper
equipment.
Under Cab Battery Access
The vehicle is originally equipped with
three or four batteries. These procedures
apply to batteries that are located in the
under cab access step battery box.
The battery compartment is located on the
left side of the vehicle, under the cab
access steps.
