turns out they kernied the neutral at service drop for the barn.there are three weather heads on the pole and it looks like a birds nest up there.I continued to have same problems today, so I am going to run a new underground service tomorrow for the barn and discontinue the overhead service.
Its either an insulation breakdown in the ungrounded conductors feeding the barn (which are 30+ years old) or I have lost a neutral at the bird nest.
Either way, this was definitely a learning experience.
I need to invest in a megger, whats a good name to get ??
