What my post told you is that not always the pins are "B, C, E" = pin 1, pin 2, pin 3. You have to check the datasheet for your current transistor. The other post told you that there is a diode connected with the transistor and when you measure you are not actually measuring the "NPN" transition of the transistor, but you are measuring the "PN" transition of the diode. A transitor is a "double diode" a diode is a "half transitor" in terms of how they are built.
