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.
