Grounding the S terminal will only tell you if the sender needle moves it's full range. If the sender had the proper resistances when tested in the cup of hot water, and the gauge does not read the proper values when that sender is wired up directly (known good wiring) in the same hot water then either it isn't compatible with the gauge or the gauge is faulty.
