@rdtsc If BE and BC are open with reverse polarity AND CE short you have violated KVL or in-circuit assumptions. and the former is not possible.
@GregoryKornblum We're sorry, we couldn't find the page you requested.
@ThomasWeller Whatever it was, thermally cracked, sitting next to grid connected MOV in an appliance, I would expect it to be a fused power resistor in milliohms which heats up with 8x power surge starting a motor/pump but acts as a fuse. The reason is these cost less than fuses but serve to soft start motors so the lights dim less when the motor starts. The value of resistance of a warm fuse is my guess for that appliance rating.
All MOV's must be fused to prevent their damage. So either it was a rusted motor bearing from bleach fumes causing increased surge current on start or a large grid over voltage transient from a lightning storm.
@TonyStewartEE75 and Marla, I have saved the offending BJT for further analysis. From what the datasheets mention, it's just a general-purpose NPN. Was used as an open-collector output in a typical industrial setting. Showed a couple of people here and they are all as stumped as me.
@rdtsc as a 3 port network, you would have to monitor 2 with a scope while using DMM diode test to debug wrt the black lead to DSO gnd. Then you may see the charge true circuit, perhaps a PNPN junction.
