Can someone tell me what temperatures the tick marks on this temperature gauge represents?
that's exactly what you have - cold (or not working)/ all good / going up hill pulling a trailer on a hot day/ OH CRAP!! PULL OVER! my wife got me one of those Lazer heat guns, verified my gage.I run a mechanical temp gauge (like a thermometer basically) and a thermostatic controller for the fan.
Not a big deal at all really but since they agree with each other on the temps it makes it kind of a verification that is nice.
The thermostat for the fan comes on at 210 according to the settings on it, and when the fan comes on the gauge says 210 on the nose.
There is no way you will do anything but guess until you can verify temps in degrees.
Now I get to mess with you a little.

I'm trying to calibrate a fan controller using these tick marks.
The 3 little dots at bottom of screen are the factory calibration targets. I could go to the book and report what temp that middle dot ( 23 ohms ) represents. Those targets cant be seen once the gauge is installed though.
If it helps, when the gauge was new, the first heavy hash mark ( shown as "pretty good" above ) is 34 ohms, approx' 180 degrees, and where OEM thermostats begin to function.
Thanks for the replies so far. I was afraid that would be the answers I would get. I'm installing electric fans and using the Pac 2750 as the fan controller. I'm trying to map the controller to my temperature sender by programming temperatures in based on the tick marks on the standard gauge. Assuming the standard gauge is operating correctly, I assume the marks represent some predetermined temperature. I may have to use the temperature selection on my Fluke to verify and calibrate the controller.
Trailbeast that's how it usually goes.
