If the diode is in shunt from plus to minus, and a reversed polarity 
plug in is done, the diode bypasses the current, if the cathode was 
installed toward the normally positive power connector pin.  Then, if 
there is a fuse ahead of that diode, it opens and the radio components 
are saved.  No drop due to the diode.
