Fuses
The fuse box is located under the fuel tank.
To access the fuses, remove the cover (1, fig. 64), which
shows the positions and amp ratings of the fuses.
The fuse located nearest to the battery protects the
electronic regulator.
Remove the protective cap (2, fig. 64) to access the fuse.
A blown fuse can be identified by a broken filament
(3, fig. 65).
Important
To avoid possible short circuits, switch the ignition
key to OFF before renewing the fuse.
Warning
Never use a fuse with a rating other than that
specified. Failure to observe this rule may damage the
electric system or even cause fire.
