Page Contents:
In this article, you will find information about the fuses of the Ford F-650 / F-750 (models 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, and 2010), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Ford F-650 / F-750
If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components. To remove a fuse use the fuse puller tool provided on the fuse panel cover.
Caution!
- 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.
- Always disconnect the battery before servicing high current fuses.
- Always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
Location of Fuse Boxes
Passenger Compartment Fuse Panel:
The fuse panel is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses.
Power Distribution Box:
The power distribution box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle’s main electrical systems from overloads.
Relays (2000-2008):
The relay box is located on the rear crossmember.
