The two main fuses (C) are located on solenoid starter
(D). Remove the fuse cap (E) on both fuses to reach
them.
A blown fuse is identified by the interrupted center
link (F).
Near the solenoid starter there are two fuses: a 25 A
(G) fuse and a 30 A (H) one.
Important
Switch the ignition key to OFF before replacing
the fuse to avoid possible short-circuits.
Attention
Never use a fuse with a rating other than
specified. Failure to observe this rule may damage
the electric system or even cause fire.
