2010 Ford F550 Fuse Box Diagram (Power Distribution Box)

The power distribution box of the 2010 F550, situated in the engine compartment, acts as a vital central hub for high-current fuses that serve as protectors for the primary electrical systems of your vehicle. These fuses are instrumental in ensuring the safe operation of electrical components by preventing overloads and potential damage.

Here are the steps to open the hood:

  1. Inside the vehicle, pull the hood release handle located under the bottom left corner of the instrument
  2. Go to the front of the vehicle and release the auxiliary latch located below the passenger side of the
    grille, next to the headlamp. Slide the handle to release the auxiliary latch.
  3. Lift the hood until the lift cylinders hold it open.

If you have recently disconnected and reconnected the battery, it is recommended to refer to the Maintenance chapter of the Owner’s Manual for precise instructions on how to replace the vehicle’s battery.
