G1800 will not crank. Starting protocal followed (on seat, pto disengaged and pulled back, foot on brake), no go. Tried jiggling pto handle and tapping on starting (worked in past), no go. Checked power to starter, ground wires, and safety switches: all good. Checked fuses: all good. Checked black/white wire running to starter solenoid: no power, traced black white wire back to mystery box on opposite side of engine. Continuity good from solenoid to mystery box. Continuity good from mystery box to ignition (black yellow wire). Mystery box is 3 inches square and .5 inch thick, with bunch of wires leading to and from. Jumped power sending 12v to the starter solenoid and tractor starts up and runs (had key on and did the pre heat protocal prior). Key turns engine off. What is mystery box? What else to check? http://www.orangetractortalks.com/kubotagallery/?image=258
