Electric Cord..."getting the Genie back in the bottle" - lol

No, but I ended up taking the cord completely out and using a conversion kit for a detachable cord. The factory used wire nuts to connect the cord to house wiring to the breaker panel and the wire nuts vibrated loose on the neutral wire and shorted out.
