Ok.. I decided to come back up to camp today, so I can hopefully fix this before the weekend.
I confirmed there is zero volts at the red wire at the thermostat. I hooked my negative probe up to 2 known good grounds this time (the breaker panel frame and a nearby outlet). So I went back to the furnace and confirmed that I still have 12V at the blue wire connected to the furnace circuit breaker. Then I just started working back from there. In the access panel where the plastic 6-pin connector is, I confirmed that I get 12V at the blue wire on one side of the plastic connector, but not on the other side. This is the blue wire that supplies power to the thermostat (i.e. it's the one that's connected to the thermostat's red wire).
Are these connectors something I could find at the hardware store? Again, here's the pic that shows it..
I jiggled the connector around a bit, but no change in the voltage.
Thanks again, guys.
