I don't believe the stepper motor itself should be groundedPerhaps the warning is telling you it's grounded when it shouldn't be, English can be quite ambiguous at times. Don't take my word for it though.Actually Guzzidiag has a routine for testing the stepper.
If it is the stock metal body stepper best replace with newer plastic one. Check which one you have. The service manual tells you which pin is ground, look it up & clean pins.The stepper is in the center of throttle body rails.
Steve,How would I go about replacing the stepper motor if need be? I am going to go ahead and buy a new one while they last at the $350.00 price as I have seen them for just south of $800.00.
That's a bugger, I sold my spare as I don't have the B1100 any more for 45 quid only last week!Look for the Ducati version too as its the exact same partI also put together a little circuit that would stroke the ICV on the bench. If you're interested let me know and I hunt down what I used
Thanks tris! that would be great...
