In this article, you will find information about the fuses of the Ford F-650 / F-750 (models 2021, 2022, 2023, and 2024), 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. Use the provided fuse puller tool to remove a fuse. It is 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.
To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
Location of Fuse Boxes
Passenger Compartment Fuse Box: The fuse panel is in the passenger footwell. Remove the panel cover to access the fuses. Pull the fuse panel cover toward you to remove it. When the clips of the panel disengage, let the panel fall easily.
Engine Compartment Fuse Box: The engine compartment fuse box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.
