would replace

the shorted origi-

nal and then not

be able to figure

out why the board was still faulty. If they took out the new diode,

it measured fine. And the other diode incident was a DO-201

packaged diode. The shorted diode on the PCB was replaced, yet

the board would not work. After checking everything several times

over and getting advice from a work mate, we noticed that when

compared to a working PCB the meter leads had to be swapped to

get the diode to conduct. The Diode was in the PCB the same way

around but the junction inside the case was reversed.  So now I

know that I need to check that the diode not only conducts one
