Now to just add the relay and hook it to the compressor and.... I start smelling smoke.... A test i ran at least a dozen times, but now it doesn't work. I look around and see this:

The neg battery terminal has cooked through. I hope I didn't fry my thermostat... I look around and everything seems to be wired correctly, the only difference between my successful test run and now is the addition to the cooling circuit and the relay, and those are on a different power supply than the thermostat... I think I am done for the day, I will scratch my head over this one tomorrow. Now to spend some time with the neglected feeling SWMBO.
So what caused the cooking? Maybe I missed it in the thread somewhere. Everything still going well? No sparks, fires, electrocutions? This is a cool project, and I may get the courage to try it someday. I am a little afraid to do my own electrical work on something like this where you have to modify parts. Changed a light fixture last weekend and was kind of expecting to see smoke afterwards.
