Tracing Circuits that are Shielded.
Quite often you will need to trace circuits in areas that are shielded from the
SMART 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 fi nd that the signal does not exit the shielded area,
then you might need to remove the shield and probe further. (See: “Verify an
Open Circuit” pg. 23)
