Fuses
IMPORTANT: Always carry spare 2‑, 15‑, and 20‑amp fuses.
The electrical wiring circuits on the engine are protected from overload by fuses
in the wiring. If a fuse is blown, try to locate and correct the cause of the
overload before replacing the fuse. 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
the band is broken, replace the fuse.
2. Replace the fuse with a new fuse with the same rating.
