Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet; verify it is grounded and is free of other wiring abnormalities.
Notify the user or owner to correct any deviations. As a work around, check the other
outlets to see if they could be used instead.
Change another probe to confirm if the fail is caused by console.
Inspect wiring for bad crimps, poor connections, or damage.
If the leakage current measurement tests fail on a new unit and if situation can not
