Tracing Circuits that are Shielded:
Quite often you will need to trace circuits in areas that are shielded from the
receiver. This doesn’t have to be an impossible feat. Sometimes just a little
logic and planning can overcome many obstacles. If your circuit enters a
shielded area, consider if it may have an exit point as well. If you receive a
signal going into a shielded area and a signal going out, you can consider the
problem not in the shielded area. Since you found the exit point of the circuit
exposing the wire is unnecessary. If you find that the signal does not exit the
shielded area, then you might need to remove the shield and probe further.
