Replacing the fuses
The fuse box, which contains the fuses
for the individual circuits, is located be-
hind panel B. (See page 6-7.)
TIP
The main fuse, which is in a different
and hard-to-reach location, must be
replaced by a Yamaha dealer.
If a fuse for the individual circuits is
blown, replace it as follows.
1.
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to
avoid causing extensive dam-
age to the electrical system and
possibly a fire.
[EWA15132]
TIP
tool kit. Use the tongs to remove and
install a fuse.
