Fuse Replacement – Electric Start Models
IMPORTANT: Always carry spare 20 AMP Fuses.
The electric starting circuit is protected from overload by a 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. Replace the fuse with a fuse of the same
amperage rating.
1. Disconnect fuse holder, and remove fuse. 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 amper-
age rating.
