With a resistor you can get it to read correctly in *one* place.  The
farther the needle gets from there the more inaccurate it is.

On a properly calibrated gauge, being fed its correct 10.0 volts, 265
ohms to ground will make it read at the bottom edge of the
"transition zone," and 35 ohms will make it read just at the
beginning of the overheat zone, and will start the blinker going.
