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 ?

GSS · **Reply #4 on:** January 10, 2014, 02:26:44 am

+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.

TomJohnston · **Reply #8 on:** January 10, 2014, 02:07:45 pm

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...

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.

gashousegorilla · **Reply #11 on:** January 10, 2014, 03:47:02 pm

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.

Ducati Scotty · **Reply #12 on:** January 10, 2014, 05:00:40 pm

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.

This is so much better than what we Got - naked wires, loose connections, no reference which fuse is which -

!

Here is one for direct comparison of where we were a few years ago -

Ducati Scotty · **Reply #16 on:** January 10, 2014, 07:23:20 pm

Now THAT looks more like my bike!

Royalista · **Reply #17 on:** January 10, 2014, 07:57:57 pm

Yes, I intended to post a picture of my installation but Singg5 beat me to it. The new style looks tidy and all that, but hey, the old style has its charm.

Ducati Scotty · **Reply #18 on:** January 10, 2014, 08:02:24 pm

That charm can fade at late hours and in heavy rain

gmmechanic · **Reply #19 on:** January 11, 2014, 04:09:29 am

gremlin ...so right...the mere spinning of the rear wheel bearings can impart a slight charge in the frame...in the old days no problem but now if it should discharge at the wrong place and time the efi MAY pick it up...i have already installed the strap on mine as i experienced many lost ground issues working on new cars and trucks...it is a cheap pm item...

Look at that !.... Sometimes I get lucky

Pretty cool, thanks Singh

ruufman58 · **Reply #22 on:** January 18, 2014, 04:18:43 pm

My newly delivered 2013 G5 still has the old set up with the 3 20 amp fuses secured to the battery box.Maybe an early 2013.Changed out the fuses with three 20 year old Buss fuses that just happened to be in the tool chest.At least the system is very easy to understand.It would seem to be an easy convert to an up to date accessory fuse block.

gashousegorilla · **Reply #23 on:** January 18, 2014, 04:43:18 pm

In addition to what appears to be a change in the circuits with a fourth fuse..... It looks like they at least moved, hopefully upgraded !, the rectifier/ regulator. You can see in Singh's pix, just behind the box, what appears to be the R/R unit ?

Ducati Scotty · **Reply #24 on:** January 18, 2014, 08:51:14 pm

That looks like the ECU. You want the RR out in the breeze, it gets hot.

The ECU is the black thing in the box..... with all them wires going to it. I'm talking about the aluminum finned unit behind the box, that you can see a piece of.... finned to dissipate heat. It's not uncommon to have a R/R unit mounted in the middle of the frame on a bike. Singh's bottom picture Scott...

Ducati Scotty · **Reply #26 on:** January 18, 2014, 09:08:25 pm

Ah, yes it is! And a great spot for it. The alternator, battery, and RR all near each other makes for a simple and short charging circuit. If I were to rewire mine that's where I'd put it.

Scott

Yup..... me too. That out in the breeze stuff is left over from the old Zenor diode Dayz. IF that is a R/R unit there, the mounting it to the frame would also help dissipate heat.

Ducati Scotty · **Reply #28 on:** January 19, 2014, 12:46:20 am

It needs a little airflow. Ducati made a batch of Monsters with them under the seat. They burned up pretty often. But just out in the open is usually good enough. Don't worry about it being in the "hot air" behind the cylinders.

Yup... very good point. The hottest I have personally seen on the exterior of the head, at the base of the spark was 190 F , on a Dyno. So that thing is what? ... Say 6-8 inches away ? It should be ah-ight I would think ? Time will tell......
