I have a 2005 bobcat s250 which has selectable hand controls. The traction light does not come on when all safety's are released. The right stick functions normally on either type hand controls. However, the left stick will not m-ove machine at all. When I move the stick forward , I hear three beeps and get a code of 38-53. The machine does not even attempt to move. Again, when started and all safety's released, the traction light does not come on. Can someone please help me? Thanks... Greg
