Long time since I posted, just got back from one of my twice yearly trip round NW Scotland for five days. Just as I was leaving I got the dreaded speed variations of the weirdest kind! Then, nothing, so for 1,500miles I had too rely on my sat nav for speed check.
Got home and was chatting with "Pierre," who kindly donated a spare speedo sensor. Thought champion, fitted it, nothing, not even a flicker. Not sure if his is goosed. Does anyone know the resistance across these three wires at all? Or, with riding for a few miles, has something else fooked up? New one's are £124 up here

None on ebay at present.....
Any help greatly appreciated as usual.
