FUSE REPLACEMENT (applicable types)
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.
1. Remove the 6×12 mm special screw from the rear cover of the
engine switch box, and remove the rear cover.
2. Remove the fuse cover, then pull out and inspect the fuse.
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.
If you have questions regarding the rating of the original fuse,
contact your Honda servicing 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.
3. Reinstall the rear cover. Install the 6×12 mm screw and tighten
it securely.
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 Honda servicing dealer for repair.
