Topamax, just a question. Was the power in connection Delta or Wye? Only asking cause I’ve seen some high phase Delta here that does some weird stuff to old machinery. Don’t know that much about it, but I know an industrial electrician who has run into three phase motors that acted just like you explained. Like a dead short.

Same thing, close or not so much?
