2018 FORD F-650/750 auxiliary battery

12 Volt DC Power Point
WARNING
Do not plug optional electrical
accessories into the cigar lighter
socket. Incorrect use of the cigar
lighter can cause damage not covered by
the vehicle warranty, and can result in fire
or serious injury. Note:
When you switch the ignition on, you
can use the socket to power 12 volt
appliances with a maximum current rating
of 15 amps.
If the power supply does not work after you
switch the ignition off, switch the ignition
on.
Note: Do not hang any accessory from the
accessory plug.
Note: Do not use the power point over the
vehicle capacity of 12 volt DC 180 watts or
a fuse may blow.
Note: Always keep the power point caps
closed when not in use.
Do not insert objects other than an
accessory plug into the power point. This
damages the power point and may blow
the fuse.
Run the vehicle for full capacity use of the
power point.
To prevent the battery from running out of
charge:
• Do not use the power point longer than
necessary when the vehicle is not
running.
• Do not leave devices plugged in
overnight or when you park your vehicle
for extended periods. Locations
Power points may be in the following
locations:
•
On the instrument panel (two
locations).
• Inside the front under-seat storage
compartment.
• Inside the rear under-seat storage
compartment.
110 Volt AC Power Point (If Equipped) WARNING
Do not keep electrical devices
plugged in the power point whenever
the device is not in use. Do not use
any extension cord with the 110 volt AC
power point, since it will defeat the safety
protection design. Doing so may cause the
power point to overload due to powering
multiple devices that can reach beyond
the 150 watt load limit and could result in
fire or serious injury. Note:
The power point turns off when you
switch the ignition off, or when the battery
voltage drops below 11 volts.
You can use the power point for electric
devices that require up to 150 watts. It is
in the center of the instrument panel. 83

AUXILIARY SWITCHES
For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
•
When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
equipped with radio transmitters, for
example, two-way radios, telephones
and theft alarms. Any such equipment
installed in your vehicle should comply
with Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulations, and
should be installed by an authorized
dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford electrical or electronic
accessories or components to your
vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of other electrical
systems in the vehicle. The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches operate only while the ignition is
in the on position, whether the engine is
running or not. Ford recommends, however,
that the engine remain running to maintain
battery charge when using the auxiliary
switches for extended periods of time or
higher current draws.
Note:
When your vehicle has a diesel
engine, use the auxiliary switches only while
the engine is running. The glow plugs also
drain battery power when the ignition key is
in the on position. Using the auxiliary
switches, even for limited amounts of time,
can cause your battery to drain quickly and
prevent your vehicle from restarting.
When switched on, the auxiliary switches
provide 8 amps, 12 amps or 20 amps of
electrical battery power for a variety of
personal or commercial uses.
The relay box for the auxiliary switches is
on the end of the left side of the instrument
panel. See your authorized dealer for
service.
The relays are coded as shown:
