If a Fuse Blows

If a Fuse Blows
All of the electrical circuits on your CRF have a
fuse to protect them from damage caused by excess
current flow (short circuit or overload).
If something electrical on your CRF stops
working, the first thing you should check for is a
blown fuse. Check the fuse before looking
elsewhere for another possible cause of the
problem. Replace a blown fuse and check
component operation.
• The main fuse (and spare) are located on the
starter magnetic switch behind the right side
cover.
Recommended Main Fuse: 10A
1. To prevent an accidental short circuit, stop the
engine.
2. Remove the seat (page 34).
3. Disconnect the negative (–) terminal
(page 134).
4. Remove the right side cover and right air
cleaner housing cover (page 126).

10. Install the start magnetic switch (3).
Install and tighten the start magnetic switch
stay bolt (1) to the specified torque:
9 lbf·ft (12 N·m, 1.2 kgf·m)
11. Install the plastic wire band (2).
12. Connect the negative (–) terminal (page 135).

If you do not have a replacement fuse with the
proper rating for the circuit, install one with a
lower rating.
Replacing a fuse with one that has a higher rating
greatly increases the chance of damage to the
electrical system.
(4) 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 CRF.
Leave the blown fuse in that circuit and have your
CRF checked by your dealer.
13. Install the right side cover, right air cleaner
housing cover and bolts.
14. Install the seat (page 34).
