The lighting problem on the swather turned out to be a switch problem. Pretty tight clearances in the overhead console and the switch had been rubbing on the ac evaporator fins causing the switch to lose internal connection. A little work with the vise grips had it tightened up again. Bent the top terminal down so it did not contact the evaporator anymore and should be good. Those wires would have worn through pretty soon causing more problems.
Now, do I use the swather to cut down the rest of the cereal grains or wait and hope the weather will ripen them enough to straight cut? Last year the straight header never came out of the shed and I swathed everything. Too much moisture and not enough heat.
Heavy rain today so I'm glad the wheat and oats are still standing.
