Title: Repair
Notes: The cows had chewed the cable very nearly down to the nub. I had to cut some of the strain relief off to get enough conductor to splice. I added a length of cable and then spliced the end on that has a completion resistor for the thermmistor half bridge. So two splices. It compared withing 0.5C with the other IRT in the window - as good as you get without a fancier setup.
