While fighting the gauge demons (grounding, replacing the voltage regulator with a 5vdc source, all kinds of fun!) I discovered something not quite right with my new coolant sending unit. According to a post from timgr (thanks for being so thorough) the resistance "cold" should be around 73 ohms. I am getting in the crazy zone of 500 ohms cold. I thought I had too much teflon on the threads but I checked between the threaded stud and the brass cap and the body as well with the similar results. Can anyone suggest a FLAPS part number that will work on a 62 F134? Maybe I bought the wrong one? Maybe I am measure resistance wrong? Any suggestion is welcomed! Thanks!
