With a properly working thermostat, and 25vac on my red lead shouldn't I get 25vac on my white when the tstat is calling for heat?
If I'm not, should I suspect the thermostat as the back plate was replaced with no net effect?
Gas heat / Electric Cool, simple R,W,G,Y wiring
In alt.hvac, a sarcastic respondent asked if I had checked the condition???? Would someone here please explain briefly the proper TS method and "Condition check"
Thank You,

On the circuit board in the furnace, there should be 5 terminals. Take the wire off of the R terminal and use a meter to check between the R and C terminals.
Or, short out those 2 terminals with a piece of 16 gauge or larger wire. That will let the smoke out of your transformer. If you can get the smoke back into the transformer, you'll be very lucky.....
R u not supossed put a jumper across R and W at the board first while the stat is hooked up and then do the smoke test with R and C.? Kill two tasks with the same jumper wire?
