Numpty! 1100GS wiring problem

[Canuck]

Something was stopping me from pulling my panniers bags off... so I pulled harder until they came off. However... I also managed to pull off two plugs/thingies. The bike is a German spec 1100 with lambda sensor... don't think this matters but ... I have no idea.

So my question is ... what should the ends of these look like and what do they do... all rear lights are fine... I thought one of these was a diagnostic plug or something...

ANyone that can shed some light on my situation, it would be greatly received.

What are the wire colours, your pic's not great...

Guessing between the lines, one is rear brake light switch, which can be green/black & yellow/grey

I'd guess the three cable lead is for the diagnostic plug that sits on the rear mudguard, as it has three holes. The other one I think is for the American charcoal fuel type thingy.

Seen this: http://www.maxbmwmotorcycles.com/fiche/ShowImage.aspx?image=Diagrams/B0005343.png&rnd=20346975

Brake lights are fine but the bike only runs well at idle...with more than 20% throttle it shuts down. I'm confident one is the diagnostic plug (3 wires). The other one with two wires (that I can see unless I pulled one off) I have no idea... and not sure why the bike would run rough without the diagnostic plug so I'm thinking the other one must be something important...

 

[Canuck]

My guess is that it is these two plugs... if anyone had a photo of theirs that I could see I'll try to purchase and replace the two plugs and see if that fixes the problem. I'll have a look on my 1150 and see if the two wiring looms are similar in that area incase that gives me any clues.

I'll be back near my 1100 in a couple of hours - I'll pop the seat off and take some pictures if no-one has chipped in by then.

[Canuck]

Cheers Matt. I'd appreciate that!

I have the plug for the diagnostic wire which I will show to Mr BMW ocean and replace... these wires are black (white); green (yellow) and brown (yellow).

The wire that I don't know where it attaches, what plug end goes on it nor where it goes, has two wires, one green (white) and one green (blue).

Isn't it for the North American market charcoal cannister?

OK - some pics of my '94 UK model 1100

Not sure if they're slightly different style of plug though - no convoluted rubber boots on mine?...

Not sure... bike was made for the german market (1997) and was imported to the UK a few years ago. It does have the lambda sensor and perhaps instead of the charcoal canister it attaches to that... I think I best go have a good look and see what I can find. (EDIT) No my lambda sensor wires are fine and intact.

Cheers matt.. (EDIT) I just had a look and I think I still have those wires that you took a photo of... I'm going to take off the tool box and try to work things out a bit. Perhaps I'll look for missing connections on other wires instead of just two reduntdant plugs.... I'm going to go have a thorough look and see if I can find another wire missing a connector... time to put on the latex gloves methinks!

 

[MattW]

OK - just had another look.
Behind the two plugs in my pictures above, there's a wire disappearing into the base of the fuse box with a convoluted rubber boot on it. Looking at it, it might not actually be a plug / socket (although it's hard to tell) - it might just be a sealed entry into the fuse box.

Tried to take some pics but it's a bit buried:

[MikeP]

If you don't have access to one, you can pop into Plymouth and borrow my Haynes.

 

[Steptoe]

Not 100% sure from the pictures but it could be one is for the charcole canister, U.S. models, left blank on Uk models.

The other is the lead for CO pot.

.

 

[Canuck]

So here are some more photos... the wires (wrapped together in the loom) coming up together from the left of the fuse box and across behind it. You can see that there are three wires... one with the end still intact that sits in his nice little clip on the rear mudguard.

The other photo just tries to show the wire colours in more detail.

I know (or I think I know) one had a connector but was not connected to anything (perhaps the charcoal cannister thing... I just assumed it was a diagnostic plug or somethingerather!. The other one, as Steptoe, says was for a co2 pot... but my bike has a o2 probe and no pot... so I'm not sure... (wish I took some photos when I had the bike apart a few months ago). So I guess I need to buy one of those and re-wire it... is that possible or what would you guys suggest?

 

[Canuck]

So I now have a clymer manual on my lap... I can see that the plug that had an end but was not attached to anything was for the CO pot. At least that is what matched the colours on the bike and in the wiring diagrams... the other one is still a mystery. Steptoe mentioned it was for charcoal canister (redundant). WOuld having both ends off these connectors make the bike run bad if neither were attached to anything?

 

[motobiker]

My bike was a grey import. I turned it to UK spec by swapping the German exhaust for a nearly new UK spec. The bike already had a CO pot fitted which came into play when the Lamda sensor wiring was disconnected and binned.

The 1st owner had the clocks changed when first ordered (via sawbridgeworth) in early 2000.

I doubt he would recognise it now.

My guess is that the CO pot should be fitted (like it was on my bike) or some sort of specific blank. The Moronic is objecting to getting no signal... or the wrong signal.

Thanks for the tipoff. My bike still has the lamba sensor so that would negate the need for a co pot. Furthermore, the place where the co pot would be has definitely not had anything in it. By looking at the wiring diagram... the only thing that the mysterious wire would be a match (wire colour wise and location (kind of)) is listed as the timing valve... where the heck is that and would this be possible... any learned opinions.

For the record... the diagnostic plug is fine... as shown in one of the above photos.

I just wish I lived closer to steptoe!

I've had a good look at the 1150... wiring is very different so I'm not able to make a direct comparison.

I can see no obvious place where the other wire was connected or what was on the end of it... I guess I'll take off the tank and trace it back to the connectors and see if I can just replace the connector if no one has a similar wire on their bike.

Howdo, intrigued by this, went out and had a look at my bike 98 UK spec 1100gs. No cat fitted, CO2 pot installed, here's what I found. Hope it's of help. Left seat and tool tray out in case you need more photos/info.
Please excuse quality of photos, phone and an old one at that!

 

[Canuck]

Perfect photos... I'll print it off and order those parts tomorrow. Just to check though... the one with the double wire does not connect to anything does it? I'll ask bill about the co2 pot one as maybe there was something special in the end of it. If anyone knows someone with an 1100GS (1997) with an lambda sensor (o2 probe) could you ask them to look to see whats at the end of the triple wire plug thingy. I feel like I'm making progress now. Already a big thanks for Matt for the preliminary photos and thought, Steptoe for clarifying the use which led me to find it in a clymer manual, motobiker for detailing why my bike may not be running well and streetmoto for some very clear pictures! Exactly what I was after.

 

[street_moto]

Glad to be of help!

Twin wire was not connected to anything and has no jumpers or anything in the end of the plug/socket.

Triple wire as you can see is connected to a CO2 pot on mine. If you're certain yours had no CO2 pot maybe there was something in the end to replace the pot/bypass it, maybe not. Are you sure you've not blown any fuses?

Where did you pull the panniers off?
Surely the remains of what's missing is knocking around somewhere to give you a clue?


Anyrate, best of luck hope you get sorted soon!
