TWL: Repair and Testing of Shore Power cords

Can anyone give me advice in repairing a shore power cord.  When I determine
that one of the  wires does not have continuity from one plug to the other,
it is usually the plug or the connection at the plug which needs to be
replaced.  However, I may not be able to visually determine which plug is
bad. It then becomes a 50/50 guess.  With the price of 50 amp plugs it is an
expensive waste to cut off a good plug.  I am almost tempted to make my own
cords in the future so that the plugs are removable. Are there any tricks I
am not aware of which could isolate the defective plug or connection.

Marty: If you can get your hands on a signal tracer, you can follow
the wire until you come to the break. Failing a signal tracer, with
an ohm-meter connected to the pins in question, you can vigorously
flex the cord at one or the other plug and sometimes the broken ends
inside the cable will temporarily touch  giving an indication on the
ohm-meter and you have nailed the culprit. Works sometimes.

If you're not living on the edge, you're taking up too much space.
