FUSE PRECAUTIONS
WARNING: Always disconnect the battery before servicing high current fuses.
WARNING: To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
WARNING: 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.

FAQs
Fuses are safety devices designed to protect electrical circuits by breaking the circuit when too much current flows through them. This prevents electrical overloads and potential damage to the vehicle’s electrical components.
The location of the fuse box may vary depending on the model and configuration of your Super Duty.
A blown fuse can often be identified by a visibly broken or melted filament inside the fuse. You can also use a test light or multimeter to check for continuity across the fuse terminals.
You may need a fuse puller (usually included in the fuse box) or a pair of needle-nose pliers to remove the blown fuse. Ensure you have replacement fuses of the correct amperage rating on hand.
If a newly replaced fuse continues to blow immediately, there may be an underlying electrical problem that requires professional diagnosis and repair. It’s advisable to consult a Ford dealership or a qualified technician for further investigation.
No, using a fuse with a higher amperage rating than specified can overload the circuit and potentially cause damage to the vehicle’s electrical components. Always use the correct amperage-rated fuse.
Replacing a fuse is a relatively simple task and can often be done by vehicle owners. However, if you’re unsure or if fuses continue to blow, it’s recommended to consult a Ford dealership or a qualified technician for assistance.
Ensure that the fuse box cover is securely in place to protect the fuses and prevent foreign objects from entering. Follow the manufacturer’s instructions for securing the cover.
