Does this wire belong somewhere?

[Knapdog]

Could someone please help me?
I  have taken the spark plugs cover off to clean the engine and found a loose light green wire in the back. It's right in the middle of my pic and you'll see it if you zoom in.
Should this be attached to something and what is it's purpose?
I've only had the bike four days so haven't really discovered if something isn't working.
Thank you

[Valker]

Did you follow it to see if it's attached at the other end? Doesn't look stock to me as none of mine have one that looks like that.

[Skinhead]

I can't see where that wire goes, Is the other end attached to anything, or is it possible that it is a stray piece of wire that just happened to fall there during some procedure?  I would grab that free end, pull it, and see if it is attached to anything.  If it is follow it to find out what.

[Knapdog]

It's attached somewhere and doesn't appear to be s stray piece that has fallen.
As you can see it's also protruding from a plastic sleeve.
I just need to know whether it belongs to something important as if it just joined to an accessory that's been taken off then I can just blank it off myself.

[Skinhead]

You need to find what it is attached to on the other end.

Look closely. Is that solid green, green/black or green/blue. A G/Bl and G/Bu go to the thermosensor and oil pressure sensor. A solid green goes near to the fan. That’s the best I can do with the wiring diagram

It's a solid light green that's heading towards the front of the bike. It's a bit trapped by a plastic shield so I can't exactly see where it's  going.

If your radiator fan isn't working that could be why

99.9% sure that’s the ground strap that should be located on the right side mounting bolt of the thermostat housing.
It normally has a ring terminal attached to it but looks to have been ripped loose.

I think it is the ground for something.  Maybe the fan.  Look for a connector that is still attatched to a bolt on top of engine.  If not desmogged probably can't see it.   Is that not the connector right by the wire?  On the boss right behind it?

[Knapdog]

Ah. Is the red arrow pointing to the source of the problem? Is that black end bit a sheath for the wire or something else?
I'm curious to know what it is anyway. Please forgive  my ignorance.

If I can find it I'll also check your suggestion. Do I need to remove anything to access that area ? Thanks.

That arrow is pointing to a vacuum port cap.

Probably the easiest would be to remove the radiator. That heat shield may be somewhat in the way but you could probably move it enough to work around it

Having just done a teardown...some guesses....horn or oil pressure sensor....radiator switch is good too

I believe Savage has it nailed. Removing the radiator is not that hard and then we shall see. There will probably be an empty ring connector bolted to the side of the thermostat housing.

[Knapdog]

If it has come off the thermostat I can't work out how it's trapped itself under the plastic "shield" and ended up by the spark plugs. Anyway, I'll attempt to get the radiator off tomorrow for a better view.

In your picture the loose end isn't trapped. The end traveling forward under the shield is probably meant to go there. I don’t know. Maybe someone caught that wire with the shield while re installing it and yanked the wire from its connector.

I see a light green w/ black dot going to thermostat housing.  Think someone else already mentioned this one.   Anyway here's a pic of mine taken between intake port 1 & 3 on the right side looking at the thermostat housing.

According to the electrical schematic, the *opposite end* of Lg wire (A) goes to the ground bolt (B). Note that the Lg wire via the G/Blk wire is not crimped to the common Ground wire for example at (X) like the other ground wires (red arrows). Don't know why it has to be connected directly to the ground bolt. Perhaps, it is providing ground for sumpthin important and if so shouldn't be left disconnected. It probably got torn off by cleaning with those bristle brushes.

Thank you very much indeed.

For me, taking the radiator off is a faff I could without unless I have to.
Could I just earth my rogue wire to a nearby suitable bolt?

I've peered in towards the thermostat area from the left hand side of the bike and I can see an identical or very similar coloured wire securely attached...

[RonW]

Personally, I don't see why grounding the Lg wire to any other equivalent bolt won't work just as well. However I would hold off until other member chime in.

[Chrisj CMA]

According to how I read the wiring diagram. There are supposed to be two wires at the thermostat location. One looks like it has a simple ring connector not a plastic plug. I don’t see an issue with securing that to any ground if in fact that’s what it is. Removing the radiator is so easy I think it’s worth it to know for sure and you said you were cleaning. There’s lots of dirt behind the radiator you will never get to without removing it.

Same thing happened to me during a desmog.  This wire just showed up.  I  had no idea where it went.  Being solid green I assumed it was just a ground so I just grounded it to one of the bolt holes that held in the smog valves that were no longer used.  It was a bitch to get a new connector on it.  Took three of us with long needle nose pliers to grab said wire and manuver it over enough to get it crimped on and bolted up to close by ground.  Everything works perfectly on the bike, including the fan.

Peace, Ron.

[Mooskee]

What a forum.  Where else can someone ask where "Does this wire belong somewhere?, and get a detailed snswer with pics, and how to fix it! Way to go ya'll.

[RonW]

But wait, there's more ..... bare in mind that while the B end the of Lg wire can go to any equivalent bolt, the A end is bolted to the thermostat housing as if to ground the thermostat housing whatever. In other words does the A end, which is the disconnected end, does that end have to be bolted to the thermostat housing? Or does it even matter. Er, I just report, you decide, lol.

[Knapdog]

Got it after deciding to move the radiator, which as you say, wasn't difficult...



Thank you all for your help. You were right. It was the ground wire that had pulled off.
Job done.

[Chrisj CMA]

And you got her even cleaner, right?  Good job

[RonW]

Awesome. thanks for the follow up.
