Why would you carry two spare 10A fuses if none of the circuits use them? Are they just so youve a full set of fuses in case your mates on a less reliable bike needs one or is this is a brain fart from Yamaha? hmm This is from the LC2 OEM workshop manual:  |

Good question and well spotted, that's a mystery to me too??

It's probably a carry over from another model
As in nobody thought to change the reserve fuse sizes

Maybe that rating will suffice on all the circuits to get you home if the original fuse went due to fatigue rather than a circuit fault ?.

Probably a fair assumption
Even with every thing powered through the main fuse 10a will allow 130w of power
Headlight 55w
Tail 10w
Signals 45w
Brake 42w
Total 152w
Given that a wired fuse will take 1.5 times it's rating easily without blowing it would get you home
I was always surprised at that. Remember being shocked that an old rewirable household fuse had to take 1.5 times it's rated current for 4 hours without popping

What looey said. Having 2 spares at 10A means you can get away with using them if any of the others blow.

I would have thought that the 5A ignition circuit is most at risk here though? Surely there would be more chance of you starting a fire or damaging the circuit if you double up to a 10A fuse??

Yes, that is correct. Fuses are a safety feature to protect the wiring and power supply system from short circuits or over current situations. The main power feeds may be bigger, but the rest of the wires in the loom are all of a reasonable cross sectional area, so even a 10amp should still blow before the wiring melts or burns. |

Yeah not good when your life depends on it

Well observed ... wonder why 10A x 2???

Even simpler reason IMO: Traditionally Yama San has/remains a Parts assembly builder.
As in they use same, generic even, parts throughout their product range... where humanly possible.
One part fits all... pretty well
