I'm hoping someone can help with my temperature gauge sending unit on my 64. If anyone could measure the resistance of a sending unit they have, on or off the car, I would greatly appreciate it. Just measure across the 2 points in the picture. I believe it should be about 19 ohms, but I'd like to verify that. My gauge is pegged hot and I'm measuring 0 ohms. When I unplug the sending unit, the gauge goes full cold and I believe that's correct. I just put this new sending unit in over the winter, it doesn't have any miles on it yet. Thank you!

Temperature sender resistance values? You might want to take a look at this resistance chart and hopefully you'll get a better handle on your problem, Good luck!!

funny you should mention this, as i am about to swap back to my old (don't know if it's the original) temp sender. the new one i got constantly shows 250 degrees. within the next few days i'll be back around the car and i can tell you, if i can remember the damn box i put it in LOL!

i get 768 ohms when not touched yet, and the value gets lower as it warms up in my hand. this measurement was with the sender off of the car.

i forgot to measure the "new" one, so i will measure it in a day or two to see what its measurement is.
