The main fuse (C) is positioned on the solenoid starter
(D). Remove the fuse cap (E) to reach it. A blown fuse
can be identified by breakage of the inner filament (F).
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 cause fire.
