No D.C. Power at thermostat.
So I'm not getting D.C. Power at my thermostat. I can take a good +12v wire and start the fan or compressor. Circuit breaker is working and I ran the "good" +12v from there to check. Where does...

It might also come from a circuit board in either the furnace or air conditioner.
Thank you!!
Found where the red/white wire ran from the furnace loose. +12v achieved before it got too hot again today. Yesterday was miserable before I finally just ran a wire from the CBP to the compressor/fan.
