NOTE
Some vehicles may have an ultra ca-
pacitor
mounted in the battery box.
These devices have a similar shape to
a battery but have two positive posts
and one negative posts. Do not attach
battery chargers to these devices to
recharge the vehicles batteries. Con-
nect directly to the conventional two
post charging batteries to charge
them.
NOTE
Follow the instructions that come with
your battery charger
.
1. Access the battery terminals, the
batteries do not have to be
removed from the vehicle.
2.
Make sure the battery charger is
turned off.
3. Disconnect the battery cables.
4. Connect charger cables.
5. Start charging the battery at a rate
not over 6 amperes. Normally, a
battery should be charged at no
more than 10 percent of its rated
capacity
.
6. After charging, turn OFF charger
and disconnect charger cables.
Alternator
Take the following precautions to avoid
burning out alternator diodes:
• DO NOT start the engine with
alternator disconnected
(connections removed) from the
circuit.
• Before welding, disconnect all
electronic connections to the
vehicle batteries.
• Remove battery power cable and
insulate it from the vehicle.
• DO NOT run the engine with the
batteries disconnected.
• DO NOT disconnect the battery
cables or alternator connection
cables with the engine running
• Never turn the ignition switch from
the ON position to the START
position with the engine running.
• When charging the battery
(installed in the vehicle) disconnect
the battery cables.
• DO NOT reverse the cables of the
alternator, starter motor, or battery.
• DO NOT polarize the alternator.
The alternator should not be
polarized like a generator. To
ensure correct polarity, use a test
lamp or a voltmeter.
Remote Keyless Entry
The system will lock or unlock cab doors
with the key fob. The system will alert you
with parking lights when the selected doors
are locked or unlocked. There are two key
fobs provided with the system which
provide secure rolling code technology that
prevents someone from recording the entry
signal.
If you have issues with a key fob, replace
the battery and reprogram the key fob. In
some situations, the key fob may need to
be replaced and in others, a fuse may have
failed that could render both key fobs
inoperative. Contact your dealer for help if
a key fob does not work and it is not
because of a bad battery.
The key fob uses one CR2032, 3V battery.
Batteries should last approximately three
years, depending on use. Consistently
reduced range is an indicator that the
battery needs replacement. Batteries are
