If a Fuse Blows
If you do not have a spare fuse and you
cannot ride the scooter 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
scooter. Leave the blown fuse in that
circuit and have your scooter checked by
your Honda dealer.
