The rect/regulator on tractor for the kawasaki eng is not you're normal 3 terminal reg as used on kohler,briggs & tecumseh eng,the reg is a strange bird in that it has an internal circuit to monitor voltage or current in charging circuit & on tractor,internally in reg this circuit may/may not disconnect dc output from battery when it detects a low voltage/high current draw condition to protect reg/alt stator in addition to lighting dash light.Most of the operating sw's/safetys sw's & indicator lights connect to the interlock module on back of dash,problem could be loose/dirty connectors in wiring harness,loose/dirty connections at module,loose/bad connections on pc board that are sensitive to heat/vibration,bad parts on pc board,clutch coil going bad & drawing excessive current,short to chassis in wiring harness when tractor gets hot.You may need jd tech manual & kawasaki manual to troubleshoot/repair charging circuit problem OR leave for local jd dealer to repair.
