(See page 3-11 for seat removal and
installation procedures.)
If any fuse is blown, turn off the main
switch and the switch of the circuit in
question. Install a new fuse of specified
amperage. Turn on the switches and
see if the electrical device operates. If
the fuse immediately blows again, con-
sult a Yamaha dealer.

CAUTION:@ Do not use fuses of higher amper-
age rating than those recommend-
ed. Substitution of a fuse of
improper rating can cause extensive
electrical system damage and pos-
sibly a fire. @
