Servicing the Fuses
For Machines with a Smart Hour
Meter
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 78 ).
T o 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.
W ARNING
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
machines do not touch and that both electrical
systems are of f and at the same rated system
voltage. These instructions are for negative
ground systems only .
3. Connect the positive (+) cable to the positive (+)
terminal of the discharged battery that is wired
to the starter or solenoid as shown in Figure 79 .
