WARNING!
Electrical damage or battery explosion can
occur when improperly charging batteries.
Failure to comply may result in death, per-
sonal injury, equipment or property damage.
WARNING!
Batteries release gases that are flammable.
Batteries are equipped with vent tubes and
flash arrestors which vent battery gases out
of the cab. Ensure all vent tubes, flash ar-
restors and grommets are properly installed
and ensure they are clear and functioning
properly. Failure to reinstall or keep the vent
tubes and grommets clear or ensure the
flash arrestor(s) are functioning properly
could result in death, personal injury, equip-
ment or property damage.
CAUTION
Do not store other items in the battery box.
Failure to comply could result in damage to
the truck and/or batteries.
CAUTION
Properly secure battery tie downs and bat-
tery box cover when reinstalling batteries af-
ter service. Do not over tighten. Over tight-
ening can crack the battery case which can
lead to equipment damage.
CAUTION
The Diesel Exhaust Fluid (DEF) system
purges to prevent damage from freezing. If
your vehicle is equipped with battery discon-
nect switches, do NOT disconnect battery
power within two minutes of switching the
ignition key off. Failure to comply may result
in vehicle or property damage.
Here are some common causes of battery
failure:
Overcharge: this condition results from
improper voltage regulator adjustment. It
results in overheating of the battery,
warped plates, and evaporation of
electrolyte.
Undercharge: the voltage regulator is
malfunctioning, the drive belt is slipping, or
your vehicle has undergone long periods of
standing idle or short distance driving.
These conditions result in battery plates
becoming covered with a hard coating.
Vibration: loose battery hold-downs may
cause battery plate failure.
Short Circuits: these discharge the battery
by draining electricity.
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 con-
tain 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 tamper 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
