This is a tutorial on how to test if a high voltage diode is good and how to determine the direciton of a high voltage diode, in case it's not marked. High voltage diodes can be bought retail but are also often found in microwave ovens. In the hobbiest world, high voltage diodes are often used in high voltage power supplies. I had need of these high voltage diodes for experiments I'm working on to do with the Testatika and the Hyde Generator.
