6 Battery storage
When the motorcycle is not used for a
month or longer, remove the battery,
fully charge it and store it in a cool, dry
place.
EC000102
CAUTION:@ l
Completely recharge the bat-
tery before storing. Storing a
discharged battery can cause
permanent battery damage.
l
Use a battery charger designed
for a sealed-type (MF) battery.
Using a conventional battery
charger will cause battery dam-
age. If you do not have a sealed-
type battery charger, contact
your Yamaha dealer.
l
Always make sure the connec-
tions are correct when reinstall-
ing the battery.

er’s seat and the other is located be-
hind cowling B. (See page 6-5.) If any
fuse is blown, turn off the main switch
and the switch of the circuit in question.
Install a new fuse of specified amper-
age. Turn on the switches and see if
the electrical device operates. If the
fuse immediately blows again, consult
a Yamaha dealer.
