To access the main fuse, remove the left
cowling.
The main fuse (C, Fig. 172), is located near the battery
on solenoid starter (D, Fig. 172). Remove the fuse cap
(E, Fig. 172)to reach it.
A blown fuse can be identified by breakage of the
inner filament (F, Fig. 173).
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 the
specified value. Failure to observe this rule may
damage the electric system or even cause fire.
