If a Fuse Blows
10. Close the fuse box cover.
11. Install the left side cover.
If you do not have a replacement fuse with
the proper rating for the circuit, install one
with a lower rating.
Replacing a f use with one that has a
higher rating greatly increases the chance
of damage to the electrical system.

Taking Care of the Unexpected
If you do not have a spare fuse and you
cannot ride the motorcycle without fixing
the problem, take a fuse of the same rating
or a lower rating from one of the other
circuits that you can do without
temporarily.
If you replace a blown fuse with a spare
fuse that has a lower rating, replace the
fuse with the correct rating as soon as you
can. Also remember to replace any spare
fuses that were installed.
If the replacement fuse of the same rating
burns out in a short time, there is probably
a serious electrical problem on your
motorcycle. Leave the blown fuse in that
circuit and have your motorcycle checked
by your Honda dealer.
