I ride in Alaska, as early and as late as I can. Granted the temp in the fairing does not take into account the wind, humidity or other factors but it sure gives me an idea when to start looking for ice. Accurate or not - it's better than nothing.

 

You sure wouldn't be able to tell by looking at a Harley air temp gauge.

 

I would think at about 37* or colder. That is when most cars give you an ice warning.

 

If you are worried about the ice on overpasses and bridges, you should always ride in a large group of bikers, always at the back of the pack and watch for your friends to go down. I replaced my air temp with an oil temp and added a jagg oil cooler. I do agree that it is a grounding problem in answer to your original question.

 

I installed mine upside and now I really understand it's whole operation.

 

My air temp gauge works well and is accurate. I thought about exchanging it for an oil temp gauge but the oil temp is what it is and I can't control it so who cares?

 

I have a 2011. The air temp gauge seems pretty useless. Doesn't seem accurate. And how do you figure out the scale. I think the dashes are about 7 1/2 degrees - come on.

 

Mine is stuck in the mid 30's, makes me feel cooler

 

Has anybody relocated the sending unit outside the fairing? If you have, where did you install it? Do the readings on the gage, after the sending unit has been relocated, appear more accurate.

 

I use the temp gauge to remind me when I need to make a water stop for mama. She can’t handle the heat over 100.
