Try going in to programming and turning off automatic feeder cutoff, AFC. Its in where you reset the acre counter. If it works then, its the electrical plug right above the reverser motor, may look connected but pull apart and reconnect wires.
Check grey connector (n41 in manual) under floor beside pto gearbox.It is a 12 pin plug and I've seen 2 2388's with corroded pins which when cleaned or bypassed cured the problem.
