2019 Ford E-350 Fuse Box Diagram

Power Distribution Box

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.

Note:   If your vehicle is equipped with dual batteries, disconnecting the primary under-hood battery does not remove power from all circuits.The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.If the battery has been disconnected and reconnected, you need to reset some features.

Changing a Fuse

Fuses

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.

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.Fuse Types

Callout	Fuse Type
A	Micro 2
B	Micro 3
C	Maxi
D	Mini
E	M Case
F	J Case
