Odd jobs

[Kev L]

Bit of advice from the panel of experts on here please. Bike keeps popping the brake light/indicator fuse. It's happening on application of either the front or the rear brake and I have tried disconnecting each switch in succession. It started about three weeks ago so I stripped the rear cowling off and checked the bulb connections, which appeared all correct, re-assembled the bike and all was ok for a couple of weeks (which incorporated the MoT luckily) but tonight it's devouring fuses again on application of the brakes. I haven't had much of a chance to have a dig around due to the weather and failing light but any ideas would be gratefully received.

Also has anyone used anything to polish the Carbonadi engine covers? Mine have dulled down and I'm wondering what's best to use on them.

And for one last question, the surface on the carbon fibre front chain guard fitted to my bike has broken down and looks distinctly manky. Is there a way of re-finishing CF to get the finish back?

By the way thanks to Jamie for the advice on the Harris kick plates being the same as CBR600RR, I bought a set from carbon king and fitted them tonight.

T cut on the covers .
And clear lacquer on the carbon that's braking down also could try mixing some thin resin and give them a fresh coat .

As for the brake lights check the bulbs as the filaments can short the circuit .

[Kev L]

Cheers fella. The bulbs are working correctly but I will check them when I strip the tail off at the weekend.

TI will give T cut a shot as well. I'll take the surface of the chain guard down with wet n dry then give it a laquer. If it works all good, if not then I need to replace it anyway. Wish I could remember which company it came from so I can avoid them on the next attempt!

Electrical problems what a pain in the butt. So you have disconnected both switches in succession but the fuse still blows. That eliminates both switches! If after playing with the rear end and putting things back together temporally fixed things, then that may be a clue. Possibly a short in one of the wires :think Apart from testing wires for lives and earths, continuity with a 12v test light which may show up something for example a dull light so something is being drained or shorting. Behind the bulb holders would be a likely place for a fault. The only other thing you can do is back track through the circuits by disconnecting what you can and bypassing wires with a jumper wire/temp replacement. Don't forget to check the fusebox itself. Does your horn work or does that blow a fuse also?

Mmmm I shall have to look at the wiring diagram in detail, see If there is anything else. If it's blowing on the application of the brake......is that either brake or one or the other, or both at the same time? If you can work that out it may narrow it down. I'm thinking rear as that seemed to have done something when you took it apart and put back together.

I shall put my thinking cap on.

Chric will be along soon for Carbon restoration. Marty would say lacquer them. I have the same problem especially on one of my exhaust hangers where it gets the most Sun parked up.

Have you got a link to the Carbon king heel plates, any pics.

Argh just had a thought. Haven't you recently put a pressure switch on the rear or did you have that before the Harris sets. Or maybe you have disturbed something. How;s the connector from the pressure switch to the block by the battery. How do you connect that up? IIRC on mine is two very small Lucars (spade terminals) and they sit quite close together so need to be insulated.

All other items on the circuit controlled by that fuse work correctly, without blowing the fuse. The brake light pops the fuse whether the front is disconnected, the rear is disconnected or both are connected. The pressure switch has been attached to the system for over a year, whilst I had the old rearsets in place, without any ill effect, so I don't see it being that. Given the circumstances I suspect the rear light unit/bulb holders/bulbs.
I'll take a couple of shots of the kick plates later.

That sounds like a loom earthing to me. Depending on the routing, you may find that the rear section of the loom goes around or under the two ecu's in the tail. It is also easy to catch the loom with a self tapper if the seat unit or undertry is held on with those.
Try lifting the loom away from the frame al the way front to back, but don't keep fitting and blowing fuses, just stick a meter in place of the fuse and test for continuity between live and earth.
You will have to check the whole length, as the same piece of wire runs from the front switch to the rear one, then on to the lamp holderat the rear.
If Iam right, it's good news, as it coild have been any other wire, and some of those go to expensive to replace ecu boxes. Better a fuse blown than those!

[Kev L]

Cheers Tony, no undertray, other than the stock one, on the bike and rear cowl held in place with stock fixings. Not a self tapper in sight, how boring. I will have a good luck at the bike on Friday.

The holes needed opening slightly with a file to get a good fit. The gear side CBR600RR plate has a slight arc on it's lower edge, obviously to fit on the CBR but it looks good.

[lloydie]

Looks like that front chain guard needs a coat or two of resin ! I'd just use the normal stuff and sand it back smooth and give it 4 coats of clear lacquer .its what I did on my carbon clutch cover Marty gave me

[Kev L]

I'll take it off and give it a go at the weekend

[agentpineapple]

carbon finish, give the chain guard a rub with wet n dry, then re-lacquer them, I just did some gilles c/f heelguards, I put approx. 10 coats of lacquer on, theres some minor fish eyeing, but other than that, they're pretty good. just remember to polish the c/f every now and then, just to protect the lacquer....
as for blowing fuse's, I ain't got a ferking clue mate, I don't do electrickery!!!!!!!

and btw I did tell you about the cbr600 heel plates, but you never listen to me....

[Kev L]

Cheers fella. I always listen to everything you say..................then dismiss it as the gibbering utterings of a barely tamed orangutan!!!!!!

[Kev L]

Just to round this off -
1) short caused by capless bulb connecting wire bent by approx 30 degrees catching two terminals.
2) carbonadi covers like T cut & wax
3) not done yet as I've got to remove the gear side Harris to reach the bottom securing bolt.

Ta for your help all.

[VTRDark]

Nice simple fix then.
