Do not reverse the battery cables. Other-
wise, the electrical parts could be dam-
aged.
(1) Make sure the main switch (on applica-
ble models) is “
” (off) before working
on the battery.
(2) Connect the red battery cable to the
POSITIVE (+) terminal first. Then connect
the black battery cable to the NEGATIVE
(-) terminal.
(3) The electrical contacts of the battery and
cables must be clean and properly con-
nected, or the battery will not start the
engine.
Connecting an accessory battery (optional)
If connecting an accessory battery, consult
your Yamaha dealer about correct wiring. It is
recommendable to install the fuse to the iso-
lator lead as shown in the illustration. For the
fuse size, be sure to follow local regulations.
For example, for USA, the ABYC rules (E-11)
should be observed.
