1. The fuse block is located on the right side of
the machine.
2. If the fuse is blown, turn off the ignition
switch and install a new fuse of proper
amperage. Then turn on the ignition switch,
if the fuse immediately blows again, consult
a Yamaha dealer.wAlways use a fuse of the specified rating.
Never use a material in place of the proper

the electrical system which could lead to a
fire.cCTo prevent accidental short-circuiting, turn
off the main switch when checking or replac-

EBU00413Troubleshooting
Although Yamaha machines receive a rigid
inspection before shipment from the factory,
trouble may occur during operation.
Any problem in the fuel, compression, or ignition
systems can cause poor starting and loss of
power. The troubleshooting chart describes a
quick, easy procedure for making checks. If
your machine requires any repair, take it to a
Yamaha dealer.
The skilled technicians at a Yamaha dealership
have the tools, experience, and know-how to
properly service your machine. Use only gen-
uine Yamaha parts on your machine. Imitation
parts may look like Yamaha parts, but they are
often inferior. Consequently, they have a short-
er service life and can lead to expensive repair
bills.
