    how long did you let the motor run for? Is there a jumper wire on the low volt term board? are the internal lo volt wirers  chaffed together  or a screw thru them? are " the lo volt wirers not connected " mean the wirers to the motor or the lo volt wirers from the lo volt terminal board to the stat?
