Servicing the Fuses

The electrical system is protected by fuses. It requires
no maintenance, however, if a fuse blows check the
component/circuit for a malfunction or short. The
fuses are located on the console to the right of the
seat (Figure 69).
To replace the fuses, remove the cover, pull out on the
fuse to remove it, and install a new fuse.

Jump-Starting the Machine

1. Check and clean corrosion from the battery
terminals before jump-starting. Ensure that the
connections are tight.
CAUTION
Corrosion or loose connections can
cause unwanted electrical voltage spikes
at any time during the jump-starting
procedure.
Do not attempt to jump-start the machine
with loose or corroded battery terminals,
or damage to the engine or EFI may
occur.
DANGER
Jump-starting a weak battery that is
cracked or frozen or has a low electrolyte
level or an open/shorted battery cell can
cause an explosion, resulting in serious
personal injury.
Do not jump-start a weak battery if these
conditions exist.
2. Make sure that the booster battery is a good
and fully charged lead-acid battery at 12.6 V or
greater.
Note:
Use properly sized jumper cables with
short lengths to reduce voltage drop between
systems. Make sure that the cables are color
coded or labeled for the correct polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage
the EFI system.
Be certain of battery-terminal polarity
and jumper-cable polarity when hooking
up the batteries.
WARNING
Batteries contain acid and produce
explosive gases.
• Shield your eyes and face from the
batteries at all times.
• Do not lean over the batteries.
Note:
Ensure that the vent caps are tight and
level. Place a damp cloth, if available, over any
vent caps on both batteries. Also ensure that the
