Ok I agree, a thermal gauge movement wouldn't be affected by polarity, but a magnetic one would.
It has been a while since I worked on 'capillary tube and sensing bulb'-type gauges.
Me too. By the mid fifty's the gauges had changed. No more tubes to kink or oil lines to break under the dash. At least the electrical senders only leaked onto the engine/floor.
