I have an older vehicle which has an electric coolant temperature sensor located in the thermostat housing. It is a negative coefficient sensor (NTC)wherein the resistance of the sensor rises as the engine gets cooler and falls as the engine gets hotter. The gauge on the dash measures this resistance and indicates the temperature by a needle. My question is, given using the same resistance sending unit, will the gauge read differently if the truck is a 6 volt than it will if the truck is a 12v?
