Thats what I figured and it seems to be that way. At least in this case. The light came on with the key in the on position. With the key in the on position I get the oil and charge light. Thats what its suppose to do, correct? If I disconnect the wire from the temp switch and touch it to bare metal the temp light comes on, the temp switch is also new. When I start the tractor the oil light should go off when the pressure builds up and that is when I release the decompression lever. Does that all sound right?
