Suburban SF-25 bench test setup question
There are four wire going to the furnace.
Red is 12v+
White is grnd
Blue and blue are labeled "thermostat" in the wiring diagram
I have red and white connected to a spare 12v battery (w/inline 15amp fuse) but I don't know what to do with the two blue. Do I connect them to create a circuit? That doesn't seem right because there's 12v going to the thermostat. Any quick suggestions on how I mimic a closed thermostat on those wires?
Thanks,
Milt
