 Well, to wrap things up, I removed the water temperature sending unit wire and when I grounded it, the water gauge needle moved over to the hot side indicating that the gauge was working.  Then I checked the resistance from the tab on the sending unit to the manifold and it was essentially an open circuit.  I thought it might be the ground between the sending unit and the manifold so I removed the sending unit, checked the resistance and it was essentially an open circuit.  Even when I immersed the sending unit in boiling water the sending unit remained an open circuit. 

Ordered a new sending unit today.  Thanks Mark and Ron for the help and advice.  John.
