Is the intermittent nature random or is it periodic? If it's periodic it *might* be a doorbell transformer. Big maybe.

He came back a few minutes latter saying it was a door bell transformer down the street. He said since it wasn't their problem he couldn't do anything about it other than contact the customer and tell them. Well, he could not talk to them that day or the next, I suppose.
