Time for a quiz.........just took delivery a few days ago of my new 2014 Classic C5. (Thank You Wife).
Read on this sight that I should remove the Bosch and put in a NGK...DONE.....Next, get rid of the Chinese fuses. ...Woops!  The forum says 20 Amp....the on line owners manual say 20 amp...the manual with my bike says 20 amp.... trouble is , my bike has 2-15 amp and 4-10 amp which matches the little sticker on the inside of the fuse cover...........any sugestions??

Guess you got a new wiring harness.  My bike and many others only have 3 20A fuses.

For your bike I'd replace what's there with the same thing.

Congratulations on the new 2014 C5 !

Do you have a picture of the fuse cover and the row of fuses ? 

There are 3 fuses in the circuit and 3 SPARE fuses in all the bikes so far. The spare fuses have the same AMPs as those in the circuit. So I don't know why there are 2 fuses of 15 Amps and 4 of 10 Amps. (unless the factory ran out of fuses and fitted whatever was available  )

Just leave the fuses as they are in the bike right now, until it is clear what is what.

(picture of 2013 C5 below ALL fuses of 20 Amps)

 Running upgrade or change I would say.  Guess they figured out that you need a larger MAIN fuse and distribute.....  Gremlin ?

+1. Sounds like another ongoing upgrade. I would stick with whatever is in your bike.

You can first establish that your new 2014 C5 has the same basic circuit design as previous bikes, by first confirming that there are 3 fuses in circuit (and other 3 are spares) with the help of a multimeter or DC voltage tester.

The sequence of fuses and their arrangement can then be compared to older C5's.

Even though RE sometimes changes things without informing anyone or without updating manuals but there have been cases of inconsistent manufacturing practice - and not inherent design changes.

One possible reason for using lower amp fuse would be to protect the wires in harness from burning out.

Also look for additional fuses by tracing some of the wires to see if RE has introduced fuses in other places and brought more significant changes in the circuit.

the 2013 b5 i bought a few months ago had this fuse set-up

That's the cleanest RE setup I've seen yet.  Very nice!

To the original poster -

While you're poking around the wiring, do yourself a favor and turn the handlebars all the way to the left and tape up, zip tie, and flex-tube any bit of the harness that touches the back of the nacelle.  Also get some grounding strap and stabilize the grounds between the front and the frame, the battery and the frame, and the swing arm and the frame.

To AZCATFAN.......Why to the swingarm??

To AZCATFAN.......Why to the swingarm??

My apologies, I meant subframe.  Usually in the course of modifying and personalizing a bike folks will install lights and other gadgets on the subframe without considering how well everything is grounded.  I typed swingarm, but I meant subframe...

To AZCATFAN.......Why to the swingarm??

actually, not such a bad idea - considering the swingarm bush is poly and may not be the best conductor.  That spinning rear tire is sure to generate some static charge, strapping across the swingarm bush MAY reduce discharge noise in the system ground - thereby aiding in stablizing the EFI controller.

  My guess would be... without seeing it.... Is 1 main 15 amp fuse and 1 spare 15 amp fuse.  3 active 10 amp fuses for the circuits, and 1 spare 10 amp fuse.

The fuse block is in a rubber case that hooks on a clip inside the box. It's easy to slide it off the clip and pull it out a little to inspect.  I suspect that if you look at the bottom you'll see that a few fuses are not connected.  These are your spares.  And yes, that is a tidy arrangement.  I have one of the earlier bikes and my wiring is pretty haphazard.  I'm glad to see they're cleaning it up.

WOW ! I am impressed that there is a REal colored and printed sticker on the door, not just a hand written note ! So RE is serious about improving quality. Compare that to older bikes of few years ago - no such info on fuses / wiring on the bike.

Can you post a picture of the sticker so that we can see the details of these fuses and their location in the circuit.

@GHG: Yep ! Agree with your observation that there is one spare fuse of 15 and one of 10 amps.  So there are 4 fuses in the live circuit.
