FYI, your attachment isn't working
UPDATE:
I was surprised. It seems exponential in that it grows really fast at the end. But because of that and the fact that I had a analog volt meter I was unable to get accurate readings towards the end of the curve. And after 11v at 1/2 way up to high, it was such a minor change from 11v at 1/2 to 12v at 3/4. I assume 12 is the max and it goes by an order of magnitude of .25v towards the last 25%
Low = Cold temp
High = Hot temp
1/3 = needle is at 1/3rd between Low and high
1/2 = medium
3/4 is our end point = hot and turn on
Full or high = broken system or bad food
Battery read 14v with the generator on
Low = 8v
1/3rd of the way to high it was 11v
1/2 of the way it was 11.5 estimated. Towards the end it was such a slow difference along such a big adjustment on the gauge.
1/2 to 3/4 of the way was around 12v and hard to differentiate.
So I would like the circuit to buzz and blink the LED at 11.75ish (This would be the Ux trigger point right?) to start and be safe and understand what to do. I could then see when it turns on or go buy a digital volt meter to get closer to "hot" aka 3/4. However now I have a starting point with 11.75 volts to turn on the switch and to be safe in calculations. Having the calculations and diagram will be great. I can refine them when I get a new digital volt meter, if my mom will let me get one.
I'm not an engineer or anything, but when I go to college I think it would be interesting so I want to start getting into it now with my ideas. Your help would be awesome.
