Fuses
The main fuse box is located on the left of the battery
(fig. 62).
The fuses are accessed by removing the protective
cover (1), which shows the ampere ratings and
mounting locations.
Only six fuses are connected to the system, with two in
reserve.
The 40A fuse (2) on the right of the battery (fig. 62)
protects the electronic voltage regulator.
To access this fuse, remove the protective cap (3).
A blown fuse is identified by a broken filament inside
(4, fig. 63).
Important
To avoid possible short circuits, switch the ignition
key to OFF before replacing the fuse.
Warning
Never use a fuse with a rating other than the one
specified. Failure to observe this rule may damage the
electric system or even cause fire.
