For the 20kV diode you checked last, why couldn't you use a DC power source instead of a transformer? Also, why didn't you flip over either of the high voltage diodes? Thanks much for the GREAT video!
Thanks a lot. You are an excellent teacher. Explained step by step not fast at all. Great. Look forward for many more. This js my first experience with you.
Why do you need to add a 3.3 KOHM resistor in series for the circuit to measure the diode voltage drop? Can’t you just connect the diode directly to the voltage and measure? Or you want to limit the current to try and save the diode
You can’t. You need to make an oscillator circuit to drive a transformer off of a dc power supply (a battery or rectified wall power, any dc power source you look for) and then rectify the output of the transformer
Thank you so much Sir for sharing such a valuable information. Just guide me with I want to replace old diode which is R 360 pls suggest me with what suitable value diode can i replace Awating for your response from India And God bless you
I dont think id use the led tester. All of my diodes read the same voltage drop except for one, it must have had just a few internal diodes gone bad and had a voltage drop of a few volts less, I believe it was underperforming compared to the others and it wouldnt have been recognized with the led test.
I am a new Sub after watching this great video and explanation. Love the last tester, going to make me one now. It looks to make testing hv diodes fast and easy.Thanks for sharing. Just1
Some simple early radio receivers used a "cat's whisker" diode which has a point contact between a fine wire and a suitable crystal (not bonded). Try searching that term or crystal radio, you might be able to make one quite easily!
Which source voltage can i use if i am testing diode of 125kv. Thanks
Thanks Ludic, been watching your videos for years, once again you helped me out.
Thanks! just used this method to find the bad diode in my voltage multiplier. Replaced that one bad diode and it started working again.

Thanks much for the GREAT video!
Using AC allows you to use two LED´s to check for good diode and shorted diode
Thanks a lot. You are an excellent teacher. Explained step by step not fast at all. Great. Look forward for many more.

Thanks glad you like it
Why do you need to add a 3.3 KOHM resistor in series for the circuit to measure the diode voltage drop? Can’t you just connect the diode directly to the voltage and measure? Or you want to limit the current to try and save the diode
Yes it is for limiting the current in diode
how to convert a higher current like 100 amps dc to a higher voltage on the output dc without a transformer ?
You can’t. You need to make an oscillator circuit to drive a transformer off of a dc power supply (a battery or rectified wall power, any dc power source you look for) and then rectify the output of the transformer
What is the power rating of 3.3 KOhms resistance u used in series of the diode?
It's not that important, 0.25W will be fine because it's a small current and it's used for a short time.
Excellent explanation and demonstration. Thank you.
but if you invers the hv diode in the last circuit the blue led is on alone
Thank you. I was wondering why I couldn’t get a reading on my microwave diode.
Best demo and explanation of hv diodes so far! Thank you! AAA+
This method is genius. Thank you!
Very nice explanation
Thanks!
The gray strip is the + side of the diode on my golf cart
Good information, thanks for sharing 👍
Cheers
saudações do Brasil a todos. essa ideia de usar resistores é muito boa. esse vídeo foi muito útil. parabéns. sucesso.
Saudações

Awating for your response from India

Very interesting video and pretty good information. I can't prove Ani of those diodes neve before. thanks again and again.
Heartiest thanks 4 mirror feeling explain
thank you, that was very helpful I especially like your test circuit with the two LEDs. a big thumbs up and a sub from me mike
instablaster...
@@walkerrandall3044 so, what is an instablaster...?

Very educative regards
Awesome Video!
Noikot vinasi, very good to learn
Thank you for the information. From Davao city Phillipines.
Good video
Thank you
✌
Good job thanks
thanks
Thanks👍
Thanks
Tested a high voltage diode today using a multimeter ...it read zero.....told the client that the diode was bad....😭😭
nice video
Thanks a lot.
😊
Thank you sir
Thanks LS :)
How about MAKING a diode ? ;]
He already did high voltage diodes. If you mean the semiconductor it is not that easy. It is possible to create primitive diodes but not a proper one.
Yes a proper one requires high tech equipment and lab
