2000 Curvy

Pretty much everything electrical seems to have gone on the SV - happened last night.

I've now got no speedo, no rev couner, no neutral/oil lights etc, (the only dash light that works is main beam when I flash it).

The heated grips seemed to be playing up last night, I'm wondering if I've popped a fuse somewhere? Is there a main fuse that would take out all of the above in a one'r?

Cheers

I have the same issue on my K6. Prime suspect is the connectors behind the headstock, I just haven't got around to sorting it yet.

Fuse! Mine was faulty and cut out on one one night whilst Chris Numbers was following me. Its the 15 and I think may be marked as signal, but not sure.

JamesMio

Brilliant, cheers lads - I'll have a quick ratch about at lunchtime. Daft question (spot the amateur), fuse box is under the main seat isn't it?

that was my first thought, yes it's marked as signal - or the one that affected my dash lectrics was.

Yep under the seat above the battery, crack open the box and swap the fuses (there's usually some spares in with the others), you may need some pliers to get them out if you've got little girl hands.

Ok, thanks.

I've got no headlights / indicators either by the way - likely to be the same fault do you think?

try the fuse marked lights (I think??)
Infact inspect all the fuses anyway but swap the signal and lights one (if it is called lights) see how you go, may well be knackered wiring up front end though (I hate electrics :()

You also have a fuse on the starter relay, as all the power in the bike goes through there. Its a 30amp and there should be a spare next to it. Its on the right side behind the saddle shutter (the black triangle), though it could also be that the starter relay has broken down as they tend to corrode, in which case your need a new one. As they break down you tend to get intermittent electrics on the bike depending on the circuit load.

oops doesn't matter

plowsie

13-03-09, 09:43 AM

Hmm, you sure you haven't got front lights? Rear light didn't work on mine when it went, but the front lights are on a seperate fuse...hmm, interesting. Think check your fuses then as Grinch says, check the 30.

JamesMio

13-03-09, 09:55 AM

Thanks - I'll double check it again and come back to you.

Aha, see, curvy, and no indicators etc. That'll be fuse 4, signal. Fuses 1 & 2 are headlights (lo & hi). Fuse 3 is ignition & 5 is the instrument cluster.

The signal fuse is the 15A one, with 10A either side of it.

try the fuse marked lights (I think??)
Infact inspect all the fuses anyway but swap the signal and lights one (if it is called lights) see how you go, may well be knackered wiring up front end though (I hate electrics :()

See above. :)

I was hoping someone knew of an eastern European midget I could rent for half an hour or so. The connectors behind the headstock are nigh on impossible to get at (after going to the trouble of removing airbox and throttle bodies even!!)

Your lucky you got summat...I got nadda.
Soembody was supposed to have solved my electrical problem. It always seems to reappear when I'm looking forward to a day of meee time. I am currently taking off all my fairings, and doing to fffing job myself.
Blown fuse....again. Somebody was supposed to have checked the wiring loom round the headstock etc. Guess what I've just found???

So just tape it up, and check the rest? Will that be enough?

If you have a wire that's rubbed on the frame or somewhere - so long as it's not gone through the metallic core of the wire, then yea, just insulation tape around that wire to isolate it, then more tape around the bundle of wires to protect it in future.

13-03-09, 12:10 PM

i use ignition sealant too on everything

dizzyblonde

13-03-09, 12:38 PM

now then, just fettling round the loom over the left side of the nose cone. bunch of wires there, I've found a pink one that has worn through, a fine thread of copper is just severed from the core, can I just wrap tape round it, or do I have to do something to it first?.....bearing in mind that there are no so called experts at home, and theres just me for the next million hours!

Grant66

13-03-09, 12:57 PM

If your talking about a single thread then just wrap the individual wire to cover the gap in the insulation (making sure the fine thread isn't sticking out), then wrap the a bit more (tape, or use some spi-wrap) around the entire cable loom to stop future chaffing.

In case your wondering what spi-wrap is:

If the majority of the core is OK, wrap it in insulating tape and all should be well. Check all the other wires to. You might want to wrap the whole loom in an old inner tube or summat to protect against future chaffing.

dizzyblonde

13-03-09, 01:10 PM

I've taped over the very small worn part, then I've taped over the taped bit on either side to stop any moisture getting under that. I've retaped the main cover that the big bunch is coming out of. Pretty certain that theres no more, checked all the wires in that particular bunch, but now its raining :-(

I can't see anything thats around any subframe, headstock or other metal thing damaged, apart from the clutch wires(that I originally found and taped up) and a main one from the right hand clip on or there abouts. Checked what i can see under the nose cone, can't figure out how to get that off ( and can't be bothered today) but the subframe is newly pwdercoated and not damaged so I doubt anything can be bare against paint to blow a fuse.

hmmm me and my mole like eyesight seems to have found more than those that know what they are doing....beginners luck eh ;-)(read as Dizzy is seething and fed up to the hind teeth of her beloved SV blowing up)

JamesMio

13-03-09, 01:11 PM

So, to clarify... I'm probably looking at a number of blown fuses (if the signals, dash lights, head lights etc are all separate fuses?), and/or a bust Starter Relay?

plowsie

13-03-09, 01:16 PM

Not necessarily. Check the smaller fuses first.

Have you recently fiddled about with bits?

I accidently crossed indicator wires with something else when mine went like this and I managed to get my headlights flashing as an indicator too :) :lol: Then the fuses blew :( 3 of them :lol:

So check the smaller fuses first. They may not look broken, but put your spares in and check, just to clarify.

JamesMio

13-03-09, 01:31 PM

No fiddling at all of late, the last thing was fitting my heated grips around Xmas time (and they're plonked straight onto the battery).

I've had a quick look at the bike again just now, here's a proper fault breakdown:

Dash Lights/Instruments:

Main Beam (blue light) - Ok
All others - KO'd
Rev Counter - KO'd
Speedo - KO'd

Lights:
Full/Main Beam - Ok
Dipped - KO'd
Side Lights - KO'd
Parking Light - Ok
Indicators - KO'd

Heated Grips - Ok

Hope that makes a bit more sense to someone?

plowsie

13-03-09, 01:42 PM

Thing is, if its your signal fuse, that explains everything BUT your front low beam lights not working.

SO, I would say maybe your Lo Beam has blown too, check all fuses though mate.

JamesMio

13-03-09, 01:49 PM

Will do - thanks for all your help folks

Baph

13-03-09, 01:57 PM

From looking at the wiring diagram, your main/full beam lights work, as does the high beam indicator. This means fuse 1 is OK (yellow wires from the fuse box go to the lights).

If your sidelights don't work, your numberplate light shouldn't either.

If your PASS switch doesn't turn the lights up, fuse 3 is fubar'd. The indicators aren't working (you've said), and this means that the turn signal indicator & back lights on the dash won't be either. Again, fuse 3 controls these. The neutral light also takes power from the indicator circuit, as does fuel & oil pressure lights.

I reckon fuse 3 has popped. :) Question is, why?

13-03-09, 08:40 PM

I've had a similar problem myself this week (2001 Curvy)

The 15A signal fuse kept blowing leaving me with no stop/tail light, indicators, or dash, all I had was headlights.

The problem started whilst I was out playing with friends on Sunday, and a couple of those friends kindly escorted me home as I had no brake light.

After taking all of the bodywork off last night I think I have solved the problem, here is a breif list of the bits I found and repaired:

Green Corroded connectors in the large block connector behind the clock, left hand side (as if sitting on bike).

6mm hole in tape around loom under rider's seat on left side caused by bolt hold seat in place (wiring was however undamaged).

wiring chaffed and worn against frame again left side at the weld attaching the bracket/wire the rider's seat locates under.

more chaffed wiring at rear of the bike, again left side right at the back of the subframe where the loom slits off for the rear lights.

I think I've fixed the problem, but can't be certain as it was fine on Tuesday, then blew every fuse I fitted on Wednesday and Tuesday, so I know the fault is intermittent, but the problems I found can not have been helping.

Bike seems to run better now too :D

Hope you get it sorted too, electrical problems are a pain, they can be difficult to diagnose. Be patient and methodical you'll find it eventually

Doof

T'was a simple fuse in the end, but once I get a bit of spare time I'll be having a look at the rest of the electrics to see if there's anything obviously wrong (it would need to be OBVIOUS for me to spot!) that might have caused it...

Thanks again for all the help chaps

Grinch

16-03-09, 02:49 PM

Which fuse?

JamesMio

17-03-09, 08:10 AM

It was the 15A Signal fuse...

JamesMio

18-03-09, 08:12 AM

Aaaaand it's gone again!

Same problem last night (in fairness, I should probably have tested it properly in daylight, but hey!).

I went out for a quick blip with my mate (in his shiny VX220), and about 2 miles out of town the same fuse popped - no speedo/revs/dashlights/indicators/brake lights/tail lights etc.

By sheer and utter luck, we stopped at a wee village for a drink before turning back, and started chatting to a lad in there about the problem, who introduced himself as one of the mechanics at ScotSpeed (our local Suzuki dealer!). Bonus!!

His diagnosis is as has been said on here, it'll be corroded wires somewhere along the line, because of the way the bike's designed any time it rains/gets pressure washed, water runs down underneath the tank and rots the electrics like mad.

So, with that in mind I'm planning to butcher it tonight, get all the plastics off and clean up each connector as best I can and see if I can fix it properly.

plowsie

18-03-09, 11:02 PM

Yeah corroded wires do that, It was my dodgy wiring for my indis that did mine over.

JamesMio

19-03-09, 08:12 AM

I had a go at the Starter Relay last night, took it to bits and cleaned all the lovely green off them. Put it back together, reconnected the battery and now I've got nothing, completely dead.

I dare say I've loosened a wire somewhere, but I'll have another look tonight!

Grrrrr!! I hate electrics!

plowsie

19-03-09, 04:06 PM

How funny is this, moved all my wiring out the way and hid it on Saturday, patched my puncture up to get me to Rads and waheyy my 15 has gone too :lol:

JamesMio

20-03-09, 10:03 AM

AAAAAARRRRGGGHH!!!!!

Finally sorted the 'Dead' problem - one of the connectors in the Starter Relay had come loose.

Rode into work to see if cleaning up the connections has fixed it, Pop - 2 miles away from home the fuse goes again.

Grrr!!! I don't think I'm going to be able to avoid stripping the lot down and going at it bit by bit (which is a bit of a nightmare with 'limited' technical expertise!)

plowsie

20-03-09, 10:04 AM

Indicators was what is blowing mine, I'm taking it apart in the courtyard at work today. Ahh well.

dizzyblonde

20-03-09, 11:19 AM

To find it, you'll end up taking every piece of plastic off, cleaning everything, putting a new earth on it, etc etc. Then you'll turn it on, and start waggling, and the first set of wires you waggle will do what its not supposed to, then you'll fine tune the waggling and find one wire.......

....well we did. One solitary red wire, loose in the back of a connector block, one nip and voila, no problem any more.
I do hope you find it, its been doin my hesd in for weeks, I even resorted to riding around without the green cover on the relay and side panel, so changing main fuses was easy :-(
So far this week it hasn;t blown once, but thenI'm waiting for it to go spectacularly when I've something important to go to....like the Peaks ride:rolleyes:

BTW have you checked up the front end? My red wire ran the rev counter too.

plowsie

20-03-09, 01:33 PM

Todays Science lesson for me.

Q. If you try connecting up the indicator wires to each other, hit the indicator switch, will it blow the 15A fuse?

A. Yes, yes it will.

Was it a fair test student? Hello no Sir, its cost me £7.

I bought 9 fuses lol, to cover any further mishaps, never know when you might need a fuse and nowhere ever has any so I've stocked up.

toffo

20-03-09, 08:37 PM

This is doing my head in as well, thats three 15A fuses gone now. Every time i think it is ok it goes again, but frustratingly, not straight away. It lasted for three days last time. Is there one problem causing this? Please dont tell me i have to try and check every wire and every connection!?:(

JamesMio

25-03-09, 11:16 AM

Well, I took all the plastics off it last night and I've had a (crude) look at all the electrical connectors - I can't see anything wrong, certainly the bit that had worst corrosion was the starter relay, which I cleaned up before the last fuse pop.

Tomorrow's mission is to check the wires for any chaffing etc, after that I'm stumped!

plowsie

25-03-09, 11:26 AM

Check your indi wires mate.

JamesMio

Wee update on this:

The bike's now been stripped of it's fairings, clocks, fuel tank, air box, tail light. There were a couple of grubby looking connectors (which I've since cleaned up) but the only bit that I've come across yet that I would consider as being properly corroded was the starter relay, which made no difference when I swapped it with another one from KT's bike.

So - I've checked all the wires for any nicks/worn down bits etc, and can't find anything wrong. At one point we found that using the rear brake was popping the fuse instantly, every time for about 4-5 fuses, then it stopped doing it!! AAAAARRRGGGHH!!!!

So, it's now had a new Brake Switch (cheers Adam!) AND we've fitted a new (2nd hand) wiring loom - there's a couple of different connectors that need soldering on, but that's almost done.

Planning to get the clocks & tail light back on tonight, then finish the final connectors and start tidying up the wiring as best I can. Then cross everything I've got that's crossable that the problem has gone away!!!
