Fuel tank sending unit

Put meter on ohms scale. R x 100. Connect one lead to terminal and other to the ground case.Resistance should vary as float moves upward. Usually would be like 200 ohms and lower as float lifts. if you want precise values let me know. If no resistance change sender may be bad.
 
There is a positive and neg terminal on the sender. Should the positive go to the guage and the neg go to the ground? The tractor is positive ground or does that matter?
 
Just looked at diesel tank and is only one terminal. Tank is ground. Polarity means nothing
as you are just checking continuity.I guess in your case check across your 2 terminals of course with no power applied.
