REPLACING THE FUSES
Read page 40 (MAINTENANCE) carefully.
Never attempt to repair a defective fuse.
Never use a fuse of a rating other than
specified. This could damage the electrical
system or cause a short circuit, with the
risk of fire.
NOTE When a fuse fitted in a particular
position keeps blowing frequently, there might
be a short circuit or overloading. When this
is the case, contact an aprilia Official
Dealer.
Checking the fuses is recommended
whenever an electrical component fails to
operate or is malfunctioning, or when the
engine does not start.
Check the 3-A and 15-A fuses first and then
the 30-A fuses.
Inspection:
◆ Remove the battery cover, see page 58
(REMOVING THE BATTERY COVER) or
the front cover, see page 54 (REMOVING
THE FRONT COVER).
◆ Extract all fuses one by one and check
for blown fuses. A blown fuse is identified
by the link bar (1) in the centre being
divided.
◆ When you find a blown fuse, determine
and rectify the cause (if possible) before
fitting a new fuse.
◆ Replace any failed fuses with a fuse of
equal current rating.
NOTE When you use one of the spare
fuses, remember to add a new fuse of
equal rating to the fuse box.
◆ Refit the battery cover, see page 58
(REMOVING THE BATTERY COVER) or
the front cover, see page 54 (REMOVING
THE FRONT COVER).
