While I had the Tupperware off for the spring change I also tried to fix the stupid fuel gauge sending unit. I took it apart and checked the wires and wipers, all seemed fine. I put my Ohm meter on the connections and got erratic readings. I tightened the center nut some more and that helped but I did notice that if I put some torque on the tube the readings would drop to infinity and if I torqued the tube the other way it would read again. I tightened the nut even more and that seemed to stabilize the readings. I also noticed a small crack in the center of the plastic wire connector. I don't know if it is related or not. After re-installing the sending unit I was reading about 55 Ohms. When I went for a test ride the gauge was reading low and into the white bar. I will fill up and see what it does. Does anyone have the range of Ohms from full to empty? Inquiring minds want to know.

Thanks, Robert.

FWIW my spare unit measures 4.6 ohms full and 75.7 empty. Not sure if it works as I have never had it on a bike.

Thanks, John. I was getting a range of 6.4 to 82 Ohms. The difference could be the different meters, I was using my old Fluke. There is still no joy in Mudville though. I filled up a little while ago and the gauge went to almost full then dropped to 3/4 then 1/2 within a couple of miles. I think I have a problem with the plastic connector on top where the conducting pieces connect to the pins. I don't have a clue as to how to repair that.
