Ed,
From what you said, I think you took the wrong conclusion... If the temp gauge went right up when you grounded the connector, the connector was working fine.  That result would say there is something wrong with the sensor.

  Thanks folks,

  Yup, I grounded the lead, temp gauge went right to the top. I snipped off the old connector and crimped on a ew one. I'll see if this works for now.

  Thanks,

  Ed

    Jonathon is right, just ground the wire and the gauge will go all the way
    up.  Good possibility the wire is broken off.  If you need a new sensor,
    VolksCafe has them for $6, p/n 049-919-501.
