Ok so from what I can tell the BDW93C transistor is an NPN with the left leg as base.  So I put the DMM onto the diode setting (is this right?), put the red probe on the base and the black onto the middle then right leg.  I got readings of 853 and 995.  When I reverse the probes with black onto the base I get infinity for each leg.

I have NFI what scale that reading is?  I have seen some sites saying to use the Ohm settings and others the diode setting, and it says I should be getting a reading in the range of 0.3 - 0.9.

So do those readings I am getting sound right?  Is it suggesting that the transistor is ok?

If I am also going to test the diode that Pascal suggested do I need to disconnect one end from the circuit board to test it?
