Low resistance in both directions.
If it was working it would have high resistance in one direction and low in the other (direction being which end you put the positive probe on).

Low resistance in both directions. It will have flow of electrons in both directions, if it is not working the way it is designed. A diode is made to allow the flow of electrons in one direction only, when it is operating properly. A diode is a one way check valve for electrons. Try to think of electricity like water. With voltage being the amount of water flowing through the pipe. The size of the pipe being the resistance. And the pressure of the water being the amps.

I am sure Rich is correct a standard diode conducts in only one direction and the other it blocks. So the correct answer is low in both directions.
It may also be interesting to know that there is a zener diode that has a break down voltage in the blocked direction. So say if you wanted to lite a hene bulb when a phone rings you would place the zener rated at 100v between the hene and the ring wire. The ring voltage is about 90-100 so the zener blocks normal talk voltage till a high ring occures then passes to the hene bulb which lights at about 100v. Fun huh?

A shorted diode acts just like a piece of wire. What does an Ohmmeter read on a piece of wire? That's your answer.
