how can I buy the HV diode? was the number printed on the diode relevant? bec. when I go to electrical supply they just say that their HV diode is square & round shape. so I would like to know if the HV diode is applicable to any brand & model of microwave oven? does the shape of diode relevant? thank you in advance for your response.
Could you also test Diodes using Ohms, I know for smaller electronics you can, and it'll allow current to only flow in that direction... Does the same principle apply to HV diodes?
I ran into a problem using this test method - I had to set my analog multi-meter to DC voltage to see the effect, which actually makes sense. When you set it on DC voltage with no diode, the meter quivers at 60 Hz but shows no potential due to the cycling polarity. When I tested the diode on AC voltage, I got basically full line voltage one direction, and zero voltage the other direction. I didn't try it with my digital multimeter.
I'm sorry, a test cord is a simple lamp cord with alligator clips soldered or crimped on to the ends. Then you plug the end of the test cord into the wall receptacle. I've apparently confused a few people. Look for 60 volts +/- 10 volts on your meter. If you have that, the diode is good.
@bobodd5 I made this video. Are you saying I'm wrong? I've only been working on these things professionally for 2 decades and I'm breaking it down in layman's terms for people to be able to test these HV diodes themselves. I guarantee I'm right!
@Js2060 You mentioned only "test cord" - you didn't explain what the cord is attached to, and it is not apparent in the video. Some of us can figure it out, but not everyone.
nice job

Hi js2060,
I tested my diode with the same set up as yours, and I got 22 VAC. Was my diode bad?
Thanks you in advance for your response.

A test cord with alligator clips plugged into the wall. ( I mentioned the test cord in the video) Good luck :)
