Temperature gage

I have a question I have a Case Sc and put a brand new Temperature gauge in it and it doesn't work. I put it in how it is supposed to go and it just doesn't work and I don't know why.
 
Is it possible there is a bubble of air where the gage plugs in? Run it a bit and see if it starts working.
 
Is the temperature gauge the type with a capillary tube? I had trouble replacing one of those on my VAC. After about the third unit I realized that tightening the sensor into the engine head until it wouldn't leak coolant was cracking the senor bulb and the senor fill fluid was leaking out. So I put an o-ring on the sensor bulb to seal into the engine head and just snugged it down.
 
Do you realize that there is a CASE forum if you scroll down a bit. You will get more precise answers there, although this one is a general question.

I might suggest that a lot of the gauges you buy in today's world that are manufactured in various locations in Asia and other various places are defective when they leave the factory. I would almost bet that they are not tested before being packed. This would include temperature gauges along with ammeters, volt meters, and oil pressure gauges etc. And then, some of them might appear to work but do not give an accurate pressure reading.
 
I am guessing the needle is not moving off the bottom.

Are you taking the tractor out and working it or just idling it.

I have had tractors you could work lightly all day and the needle on the factory gauge would never move off the bottom.
If this is the case then congratulations your cooling system is in top shape.

Had one for over 10 years and the only time the gauge ever moved off bottom was when I had lost a fan belt on the road.

To be sure it is faulty you need to either put the sender in a pot of water or use a thermometer to confirm the coolant temp adjacent to the sending unit/probe is different than what the gauge is reading.
