I was given an old 2007 jayflight bunkhouse a short time ago and recently moved into it. It's had quite a few components pulled or replaced over the years, including the furnace.
The AC shows no signs of life no matter what I do with the thermostat, so I started reading and read that the thermostat wiring goes to the furnace, then to the AC, and seeing as all the wires there have been cut I guess it has to do with that.
There are 3 pairs of wires where the furnace used to be.
1 heavier pair of black and white wires that meter the same voltage as my batteries which I assume originally powered the furnace blower,
1 thin red and white pair of wires which are coming from my thermostat (a white analog coleman-mach unit, probably original from 2007) and measure a fraction of a volt on my DMM when the thermostat is set to heat or cool but show no voltage when it is off,
And 1 pair of wires with clear insulation, one silver and one copper, that measures 0 volts which notably come from a hole higher up on the wall than the other 2.
Am I likely to break anything by connecting the red and white pair to the clear insulated pair? I can't imagine it would fry anything given the very low voltage and amperage from the thermostat, but I just want to be sure I'm not about to send something unexpected signals. Also, any recommendations on determining which of the silver and copper are positive and negative beyond trial and error? They have no voltage, so I can't just meter them.
Many thanks in advance!
