He is attempting to identify a problem, not commission a cable. The problem will show with a low level test, a megger, or likely, as I said before, an ohm meter.
He may want to consider an AC test as opposed to your DC.
You are of course right, better to do nothing, or hire a third party to do a tan delta test as opposed to rectify the problem.
