The electric starter relay circuit and battery charging circuit are
protected by a fuse. If the fuse burns out, the electric starter will
not operate. The engine can be started manually if the fuse burns
out, but running the engine will not charge the battery.
If the fuse is burnt out, discard the burnt-out fuse. Install a new
fuse with the same rating as the one that was removed, and
reinstall the cover.
Reinstall the rear cover. Install the 6 12 mm screw and tighten
it securely.
If you have questions regarding the rating of the original fuse,
contact your servicing Honda engine dealer.
Never use a fuse with a rating greater than the one originally
equipped with the engine. Serious damage to the electrical
system or a fire could result.
Frequent fuse failure usually indicates a short circuit or an
overload in the electrical system. If the fuse burns out frequently,
take the engine to a servicing Honda dealer for repair.
