1997 Ford F450 Fuse Box Diagram (Power Distribution Box)

The high current fuses contained in the Power Distribution Box protect your vehicle’s main
electrical systems from overloads; these fuses provide the connection between the battery and
your vehicle’s electrical systems.

The high current fuses are coded as follows: 30 amp — light green, 40 amp — orange, 50 amp — red, 60 amp — blue.

Steps to open the hood of the 1997 Ford F450

To access the engine compartment of your vehicle, follow these steps:

  1. Find the hood release handle located beneath the bottom left corner of the instrument panel inside the vehicle. This handle is typically positioned near the driver’s side footwell.
  2. Pull the hood release handle firmly to activate the primary latch that secures the hood. You may need to exert some force, but the hood should release.
  3. Once you’ve pulled the hood release handle, move to the front of the vehicle. Look for the auxiliary latch, which is situated under the right center of the hood.
  4. Locate the handle or mechanism associated with the auxiliary latch and release it. This can usually be done by sliding the handle or disengaging the mechanism, depending on your vehicle’s design.
  5. With the auxiliary latch now released, you can gently lift the hood upward. The lift cylinders in place should support the hood, allowing it to stay open.

Important Notes

  • Ford recommends that high-current fuses be replaced by a qualified technician.
  • A blown high current fuse may be replaced but will continue to blow until the cause of the overload condition is corrected.
