Spilt tractor to rebuild fwd and rear clutch packs, put back together won't crank, have code EN-ENG o dash. Have power to CRS relay, can ground terminal that goes to ECM and will crank and run, remove ground to shut off.
I have a service manual my son got me from Kubota, he works a KMA in R&D dept for lawn and turf div. He doesn't deal with big tractors. I thought diode in wiring by crs relay was bad, replaced diode but still same problem.
