FUSE PRECAUTIONS
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. 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. UNDER HOOD FUSE BOX
