Wheat harvest everything fine, sat for 2-3 weeks. Went to move it, corner display (all 3) has all symbols lit up, engine speed control stuck in low. Unhooked batteries overnight - all well. Sat till now- same thing - throttle worked until seperator engaged, then quit (low idle only - lights on console change by buttons) Greenstar, speed monitors, head height, unload, swing etc... ok. Unhooked batts for 1/2 hr, dielectric greased all cab connections, no change. Will let it set overnight and see. Any Ideas?
