Normally, the 12 volt power for the A/C will feed from the furnace.


Looked into that and you are correct. Pulled the furnace cover off and there is a 12V circuit breaker that feeds the tstat. Reset that but still no display on the tstat. I did not have shore power hooked up but I would think thats not needed unless I want A/C. Tomorrow I'll get my volt meter out and do some more checking.
