The sensors work backwards to what you are thinking.  High temps or high
fuel levels produce lower sensor resistances, therefore more current to
heat the heater that bends the bimetal strip that moves the pointer.  If
there was a higher resistance in the path, that would produce a lower gauge
reading.  A high reading indicates that there is a too low resistance
somewhere, a short or something.  Are you sure you have the right temp
sensor?

If your regulator is the stock type, it should be switching at a low
frequency, several times a second, bouncing the pointer of an analog meter
around. The on/off ratio causes the voltage, that's either 12V or 0, to
average out to 10V.
