2000 1150GS Rough Running
ihmsakiwi:
Coil checked out as per spec.
Detached both injectors and turned key and got good fuel flow from both, so not fuel.
Hi Jughead,
I have just bought / ordered a new Hall Effect Sensor from Dan Cata and this will land here in NZ at under half the price as getting the part from one of the BMW agents here in NZ and there would have been a three to five week wait as they need to fly one in from Germany!!
Hell I hope that it fixes the issue but I suppose at least that should be one more thing I should not have to worry about for the next 100,000K or so.

Hi Peter
I think you misunderstood what I was trying to get at.
The one sensor on the HES plate triggers the spark, the other triggers the fuel pump (and I think the injectors). When I asked you to check whether you had fuel mist from the injectors, it was a test to check whether the HES is working, which in your case appears to be working fine.

Pull the two injectors but leave them connected to the fuel line. Face them outward and crank the motor over. If you have fuel mist spraying from the injectors, your Hall sensors are fine. If not, my money would be on disintegrated wiring behind the HES.

I would be looking at the input trigger wire to the coil or possibly spark plug leads. You may have had two plug leads failing in quick succession, thus your original problem of rough running and now no spark.
Note that both plugs fire simultaneously. (Compression and Exhaust stroke)

Thanks Jughead,
I will do some more checks tomorrow as you suggest.
I went with a new HES as I am not sure of the service history of my bike as it has had multiple owners and the service history is sketchy. At least with a new HES I can hopefully cross that off the things to replace or worry about. New plug leads are my next purchase. Peter

Hi Jughead,
As discussed I am currently in a no-spark situation.
What sort of GS-911 message could I expect to see if either of the following was present?;
No power to the coil.
Faulty spark plug leads causing no spark.
Peter
Jughead:
None at all. Not the fault of the GS911, but rather the ECU's inability to be able to detect a fault. Remember that the GS911 only displays errors that are provided by the ECU.
Since the ECU has no ability to interrogate the trigger to the coil or the plug leads, you would have to do that yourself.
In the same way you tested the coil earlier, you need to test it again via the plug leads. First test the leads individually. I think you should get a resistance of around 10k. Secondary of the coil, output to output is around 220R so testing the coil, plug cap to plug cap should be around 10.2k.
