Thumbs up Re: Testing a transformer for shorted turns

Good morning,
I tested it and it works fine. 470 Ohms at 6VDC or 1K at 12VDC are good values. I tested a small and a big transformer. Secondary shorted, no flashing.
Connect the neon without series resistor, it makes the flashing time short.
Thanks again for this nice idea!
Kind regards,
Darius
