91+/- New Holland L785 Ford diesel will not start sometimes. The engine does not turn over. Battery voltage 12.8. Seat belt and seat switch work. All lights work on the panel as they should most of the time. Interestingly the unit will sometimes start after sitting overnight. New start switch installed because I had one. I suspect the logic module must be involved unless there is a poor ground or loose connection somewhere. Sometimes there will an audible click of some relay in the bowels of the machine, other times not. Seems the longer the unit sits the louder the click. Is there some kind of timer involved here? The logic module has "Timer" stamped on it. What does the "timer" time? Suggestions as to what to try? New Logic module I suppose? Can't find this part on the net, however. Thanks
