Absorbs the energy instantly (lighting up few or no LEDs). Exclusive Schematic Diagram Analysis
Notes:
Add a BNC connector in parallel with C4 (before the comparator). Connect your oscilloscope to see the actual ringing waveform. A good coil shows >5 visible cycles; a bad coil shows 1-2 cycles. blue ring tester schematic diagram exclusive

In the world of electronics repair, few tools inspire as much curiosity—and confusion—as the . For decades, technicians repairing switch-mode power supplies (SMPS), flyback transformers (LOPT), and deflection yokes have struggled with a common problem: How do you test a coil or transformer for shorted turns without expensive equipment? A good coil shows >5 visible cycles; a
Drop a comment below. Let's keep the old analog magic alive.
A acts as a secondary winding with a dead short. This dramatically reduces the Q factor. The ringing stops after just 1 or 2 cycles instead of 10 or more.
