<<Also with regards to checking the accuracy of the gauge reading, I have a fluke meter so i can do that part. Do I just measure resistance of the resistor, then do the math shown on some other posts with regards to what temp that should equate to? Then look at the dash and see if it jives?
OK ... second part:
The best way is to take a look at the gauge when it has settled and then , without a time delay , take a sensor reading in OHMS
I leave the car running so I know we keep stable.
A better way , is to look at the temp/resistance chart and go to RS and get a high tolerance resistor and use that in place of the sensor..don't have to run car or heat it up that way.. you are just subing a known value from the chart
remember , the gauge is the single wire sensor , not the other
I will look up that spec , if u can't find it...
Also, to eliminate the =/- of the resistor, take a reading of its
value before usiong it for calibration purposes.. they are all out a bit
