Fuses
The main fuse box is located under the fuel tank.
To expose the fuses, take off the box protective cover (1,
fig. 46.1). Mounting position and ampere capacity are
marked on it.
The fuse located near the battery (fig. 46.3) protects the
electronic regulator.
Remove the fuse cap (2) to expose it.
A blown fuse is identified by the interrupted inner
E
filament (3, fig. 46.2).
Important
Switch the ignition key to OFF before replacing
the fuse to avoid possible short circuits.
Warning
Never use a fuse with a rating other than specified.
Failure to observe this rule may damage the electric
system or even lead to fire.
