    What kind of meters are you using? I've never tried with a DVM, but VOMs work really well.

    After reading the entire article this will work. Care to pick up the discussion in the Electronics Chat Forum?

    Related, but I suspect the OP hasn't read it.

    To the OP:

    A suggestion, and likely my last word on this subject in this forum, try it on a known transistor to get a feel for the readings and how it works.

    The OP is correct. The procedure will not work with an a if you are using a digital meter and it is set to Ohms. The meter MUST be set to "Diode test" for it to work.

    The typical digital meter put out around 0.2Volt on the Ohms range which is not enough to forward bias the PN junction.
