WARNING
Before attempting any work on the bat-
teries or electrical system, remove all
jewelry. If metal jewelry or other metal
comes in contact with electrical cir-
cuits, a short circuit may occur causing
you to be injured, as well as causing
electrical system failure and damage.
Charging
WARNING
Thaw out frozen batteries before
charging them. Inspect the battery
case for damage: cracks, swelling of
the case, and/or battery acid leakage.
If damage is found, replace the bat-
tery. Remove all the filler caps before
charging.
WARNING
Charger cables must be connected
positive to positive (+ to +) and nega-
tive to negative (- to -). If connected
improperly, batteries could explode.
Failure to comply may result in person-
al injury, death, equipment or property
damage.
WARNING
Always make sure the battery charger
is OFF before connecting or discon-
necting the cable clamps. To reduce
the danger of explosions and resulting
death or personal injury, do not con-
nect or disconnect charger cables
while the charger is operating.
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,
nonconducting 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, and haptic equipped
components, 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.
Battery Capacity
Using electrical components, such as the
cab heater or refrigerator when the engine
is not running, power will be drawn from
the batteries.
Approximately half the battery capacity is
required to start the engine.
If this is the case over a protracted period,
particularly during low temperatures, the
result may be that the electrical
