"A very good test you can do is to check a diode with your multimeter set to the ohmmeter setting. This is a simple test we can do to check whether it is good, open, or shorted. So we take the ohmmeter and place it across the leads of the diode. The orientation is very important. See more We first take the ohmmeter and place the positive probe on the anode of the diode (the black part of the diode_and the negative probe on the cathode of the diode (the silver strip), as shown above. In this setup, the diode … See more Now take the ohmmeter and switch the probes around so that the positive probe of the multimeter is now on the cathode of the diode and the negative lead on the anode. In this setup … See more If the diode reads low resistances in both directions, this is a sign that the diode is shorted.
