of ignition near the battery.
The procedure for checking the battery varies
for different batteries. This procedure con-

tions will help you monitor the battery’s
charge. If the battery needs charging,
consult your Yamaha dealer.
3. Check the battery connections. They
should be clean, secure, and covered by
an insulating cover. WARNING! Bad
connections can produce shorting or
arcing and cause an explosion.
