Storage the battery
1. When the motorcycle is not used for a month or longer,
remove the battery and store it in a cool, dark place.
Completely recharge the battery before reinstallation.
2. If the baterry needs to be stored for a longer period
than the period mentioned above, check the specific
gravity at least once a month, and recharge it when the
specific gravity is below normal.
3. Always make sure the connections are correct when
reinstalling the battery. The red (positive) lead is for the
+ terminal and the black (negative) lead is for the -
terminal. Always connect the red (positive) lead first,
then connect the black (negative) lead. Make sure that
the battery breather pipe is correctly routed, free of
obstructions, and in good condition.

If a fuse is blown, turn off the ignition switch and the switch
of the circuit in question. Install a new fuse of proper
amperage. Turn on the switches and see if the electrical
device operates. If the fuse immediately blows again,
consult a Yamaha dealer.
WARNING:
Do not use fuses of higher amperage rating than those
recommended. Substitution of a fuse of improper rating
can cause extensive electrical system damage and
possibly a fire.
