FORD MUSTANG 2018 Owners Manual

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 need to reset some features.
See Changing the 12V Battery (page 239).

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.
