The mechanical limiter will send higher output during warm up, makes needles move faster to where they are going. Switch on with cold stopped engine, fuel gauge responds, oil and temp don't move. If there is short in temp gauge circuit, limiter senses that and sends all it can. Current takes that path of least resistance. With the minimum of 80 ohms resistance at the fuel sender, and too much current, How would the fuel gauge respond? I don't know that it would go to 3/4 of range but I'll bet my quarter needle would leave home.
What I do know... if the temp sender path is shorted to ground, the temp gauge will die eventually.
If the limiter sticks closed the gauge with least resistance ( typically the fuel gauge ) will get lions share of the voltage, read way high. The limiter should fail internally but that doesn't always happen. Instead, the copper trace on the circuit board that carries 12 volts to the limiter will burn open as if it were a fusible link.
