Of course not ideal solution as replace the gauges.
But does work.
And is stable.
The min parallel resistance allowed is the one that
IS NOT raising the indicator from his rest position
when the engine is cold.
Sometimes happen the ground of instrument dashboard is NOT
zero ohm if compared to the chassis and this may cause
wrong reading @ high temperature where the sensor goes
very low , below 100 ohm.. but was not my scenario.
