Sounds to me you lost currant to clutch. likely rodent damage. Trace wires coming from clutch and you may find quite easily. One side of header clutch switch is used to fire up some monitors and auto header control and believe that is why head jerks up an inch or so each time switch is activated. Clutch side of switch is separate but I doubt that went bad over winter. I would start at clutch with test light and work your way back to cab while examining harness as you go. Good luck
