Just bought a house heat was on. When I checked furnace the wires were burnt and the shield was off. I rewired, turned on and lit furnace. Didn't blow up but heat is no longer blowing and burners are not firing full. Does anyone have a picture of the wiring for this model? Or give me a wiring schematic?? :confused1:
