When installing the power distribution
center cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the power distribution center and
possibly result in an electrical system
failure.
When replacing a blown fuse, it is important
to use only a fuse having the correct
amperage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
