so over the weekend I was away at deer camp preparing a food plot used my tractor all day never any issues finished work on a Thursday evening parked it. On Friday afternoon i attempted to start and it was dead. I used a jump box to start and use ran for over an hour and would not restart. Fast forward to Sunday evening returned home to unload trailer and attempted to use cables to jump start and nothing and the battery had plenty of fire there big sparks when touching clamps together. So in closing give me some ideas on troubleshooting, Thanks in advance
