I was using that diode/transistor testing thingy on my multimeter to verify two transistors I accidentally cooked in a circuit. I used some de-soldering wick. To my surprise, both still seem to work, but the circuit does not. What else might go horribly wrong when soldering? And is that a reliable way to test them? I tested one in circuit, but it passed (I think this is okay given the wiring at present). Thanks again!
