: When the pulse hits a healthy inductor, it creates a decaying AC waveform (ringing). The tester counts how many of these oscillations exceed a specific voltage threshold.
To build this circuit based on the standard "Anatek" or "Bob Parker" designs, you will need: 1x 74HCT14 (Hex Inverting Schmitt Trigger) or LM339. LEDs: 2 Red, 2 Orange/Yellow, 4-6 Green. blue ring tester schematic diagram exclusive
Would you like a detailed explanation of the using a ring tester instead (low voltage, no blue ring), or the theoretical principles behind detecting shorted turns? : When the pulse hits a healthy inductor,
