Ford F-650/750 - 2018 Fuse Box Diagram

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.

Brake-Shift Interlock
(If Equipped)
WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can
roll freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate.
If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. Have your vehicle
checked as soon as possible.
Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is in the 3 (on) position
and the brake pedal is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition in the
4 (on) position and the brake pedal
pressed, a malfunction may have occurred.
It is possible that a fuse has blown or your
vehicle
s brake lamps are not operating
properly. See
Fuse Specification Chart
(page 165).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
1.
Apply the parking brake. Switch the
ignition key to 1 (off), then remove the
key.
2.
Move the steering column to the full
down and full rearward position
(toward the driver
s seat).
3.
Remove the gearshift lever boot.
4.
Place fingers into hole where you
removed the gearshift lever boot and
pull top half of shroud up and forward
to separate it from the lower half of the
shroud. There is a hinge at the forward
edge of the top shroud. Roll the top
half of the shroud upward on the hinge
point to clear the hazard flasher button,
then pull straight rearward toward the
driver
s seat to remove.
5.
Remove the top half of the shroud.
6.
Remove the three fasteners under the
column that secure the lower shroud
half to the column.
E163185
7.
Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover.
8.
Apply the brake. Gently lift the override
disk and move the gearshift lever into
neutral (N).

Transmission
TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label.
Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 165).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation.
Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
Load the heaviest items closest
to the trailer floor.
Load the heaviest items
centered between the left and
right side trailer tires.
Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit
(page
140).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

you may restart your vehicle.
If your vehicle has a key system:
1.
Switch off the vehicle.
2.
Switch on the vehicle.
3.
Repeat steps 1 and 2 to re-enable the
fuel pump.
JUMP STARTING THE VEHICLE
WARNINGS
Batteries normally produce explosive
gases which can cause personal
injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation.
Keep batteries out of reach of
children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately.
Use only adequately sized cables
with insulated clamps.
Preparing Your Vehicle
Do not attempt to push-start your
automatic transmission vehicle.
Note:
Attempting to push-start a vehicle
with an automatic transmission may cause
transmission damage.
Note:
Use only a 12-volt supply to start your
vehicle.
Note:
Do not disconnect the battery of the
disabled vehicle as this could damage the
vehicle electrical system.
Park the booster vehicle close to the hood
of the disabled vehicle, making sure the
two vehicles do not touch.
Connecting the Jumper Cables
WARNINGS
Do not attach the cables to fuel lines,
engine rocker covers, the intake
manifold or electrical components
as grounding points. Stay clear of moving
parts. To avoid reverse polarity
connections, make sure that you correctly
identify the positive (+) and negative (-)
terminals on both the disabled and booster
vehicles before connecting the cables.
Do not attach the end of the positive
cable to the studs or L-shaped eyelet
located above the positive (+)
terminal of your vehicle
s battery. High
current may flow through and cause
damage to the fuses.
Do not connect the end of the
second cable to the negative (-)
terminal of the battery to be jumped.
A spark may cause an explosion of the
gases that surround the battery.
Note:
In the illustration, the bottom vehicle
represents the booster vehicle.

Always replace a fuse with one that
has the specified amperage rating.
Using a fuse with a higher amperage
rating can cause severe wire damage and
could start a fire.
E217331
If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm)
Belts (fan, alternator,
water pump and air
conditioning
compressor)
Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine.
Fluid leaks
Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance.
HVAC air inlet
Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equipped
with spare electrical fuses (if used), three red reflective
triangles, a properly charged and rated fire extinguisher and
wheel chocks.
Safety and emergency
equipment
Walk around the vehicle and verify all steps and grab handles,
inside and out (as well as behind), are tight and clean. Use
extreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is in
neutral (N) or park (P) (if equipped with a park position).
Starting the engine
Diesel engine:
Turn the key to the on position. Turn the key
to start when the wait to start indicator light in the instrument
cluster turns off.
Gasoline engine:
Turn the key to start, and then release it
as soon as the engine starts.
Verify pressure builds to normal operating range.
Engine oil pressure
A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches 70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115
130 psi (793
896 kPa).
Low air pressure warning
tone (if equipped with an
air compressor)
Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately.
