| Step | Test | Procedure | | Failure (Faulty) Indication | | :--- | :--- | :--- | :--- | :--- | | 1 | Basic Diode Test (Collector → Emitter) | Set DMM to diode mode. Connect Red Probe → Collector , Black Probe → Emitter . | Reads Open Circuit (OL) or a diode drop (0.3-0.7 V). | Reads 0.000 V (shorted) or very low resistance. | | 2 | Reverse Probes (Emitter → Collector) | Keep DMM in diode mode. Connect Black Probe → Collector , Red Probe → Emitter . | Typically reads Open Circuit (OL) in this direction. | Same reading as Step 1 (conduction in both directions). | | 3 | Gate Charging Test | 1. Touch Red Probe to Gate , Black to Emitter for 1 second (charges gate). 2. Move Red Probe to Collector , Black to Emitter . | After charging, you should now see a diode drop or partial conduction. | No change (still shows OL) or suddenly shows a short . | | 4 | Discharge & Repeat | Touch all three pins together with a finger or metal tool to discharge the gate, then retest. | A healthy transistor should turn on and off consistently each time . | N/A (This step confirms consistent healthy behavior). |

Here is a reliable step-by-step testing procedure using a digital multimeter in diode mode.
