2018 FORD F-650/750 fuse box

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
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. 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 you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 207).
