If a Fuse Blows

If a Fuse Blows

All of the electrical circuits on your motorcycle
have a fuse to protect them from damage caused by
excess current flow (short circuit or overload).
If something electrical on your motorcycle stops
working, the first thing you should check for is a
blown fuse (1). Determine from the chart on the
circuit fuse box cover which fuse or fuses control
that component. Check the fuse before looking
elsewhere for another possible cause of the
problem. Replace a blown fuse and check
component operation.

(1) blown fuse
The main fuse and circuit fuses are located on the
behind the left side cover.
Recommended Fuses
Main fuse 20 A
Other fuses 10 A
Circuit Fuses Access:
1. To prevent an accidental short circuit, turn the
ignition switch OFF before checking or
replacing the fuses.
2. Remove the seat (page 46).
3. Remove the left side cover (page 47).
4. Open the rubber fuse box cover (2) and fuse
box cover (3).
5. Pull out the fuses one by one to check for a
blown fuse. Always replace a blown fuse with
a spare of the same rating.

6. Close the fuse box cover and rubber fuse box
cover.
7. Install the left side cover (page 47).
8. Install the seat (page 46).
If you do not have a replacement fuse with the
proper rating for the circuit, install one with a
lower rating.
NOTICE
Replacing a fuse with one that has a higher rating
greatly increases the chance of damage to the
electrical system.
Main Fuse Access:
1. To prevent an accidental short circuit, turn the
ignition switch OFF before checking or
replacing the fuse.
2. Remove the seat (page 46).
3. Remove the left side cover (page 47).
4. Remove the start magnetic switch cover (5).
5. Pull out the main fuse (6) to check for a blown
fuse. Always replace a blown fuse with a spare
of the same rating.

7. Install the left side cover (page 47).
8. Install the seat (page 46).
If you do not have a replacement fuse with the
proper rating for the circuit, install one with a
lower rating.
NOTICE
Replacing a fuse with one that has a higher rating
greatly increases the chance of damage to the
electrical system.
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 the spare fuse that was 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 dealer.
