Did you say that you changed the water temperature indicator sender?
If your taurus is the same as my explorer, the sensor will read to ground between 73 ohms when the engine is cold and 9.7 ohms when it is hot.
Check it with an ohm meter. And let us know.
Also, if the sensor is within range, with the engine off, check the resistance to ground from the wire going back to the instrument panel. If there is little or no resistance, there is probably a short as mentioned by the M_J_RITZEL's message.
If our suggestions work, or even if they don't, let us know. Vote for us if you think we deserve it.
