Old Blue;
You can get any resistor from Radio Shack. However, this is just fooling the actual resistance from the temperature sensor by a set value. Fiddled around with a variety of resistance values and most didn't change the reading significantly until you got a resistor over 100 ohms. Then the meter never rose above empty, Figured that the resistance was too great then. I know that temperature vs resistance varies along a set curve based upon the requirements of the range so I keep thinking that the sensor from the vendor isn't matched to the range of the dash gauge. I do temperature control work for a living and know that there are lots of thermistors (temperature sensitive resistors) in a variety of ranges available. Unfortunately, they don't come in immersion styles for our engines. Think I will experiment with a variety of thermistors which I have in stock and see if any one of them matches my readings from my temperature meter. If I have any luck, I'll let you know. Otherwise, the gauge looks great sitting under 220 degrees and the engine isn't hot so all is well.
