Fuses
There are twelve fuses that protect the electric
components located inside the front and rear fuse
boxes, and one on the electric solenoid starter. There
are three spare fuses (S) in every box.
Refer to the table below to identify the circuits
protected by the various fuses and their ratings.
The rear left fuse box (A, Fig 178) and the rear right
one (B, Fig 179) are located under the seat, inside the
underseat compartment.
To access the fuses, remove the seat (see "Removing
the seat" on page page 174).
To expose the fuses, lift the box protective cover.
Mounting position and ampere capacity are marked
on box cover.
