Fuse Replacement ‑ Electric Start Models
IMPORTANT: Always carry spare SFE 20 AMP fuses.
The electric starting circuit is protected from overload by an SFE
20 AMP fuse. If the fuse is blown, the electric starter motor will not
operate. Try to locate and correct the cause of the overload. If the
cause is not found, the fuse may blow again.
1. Open the fuse holder and look at the silver colored band inside
the fuse. If band is broken, replace the fuse. Replace fuse with
a new fuse with the same rating.
