method works with the phone line connected or disconnected
from the wires going to the telephone company. A stronger
trace is usually obtained if the wires are not connected to
the telephone company.
If the wires are not connected to the telephone company,
the grounded method can be used to trace telephone wires
through a wall or ceiling. Use the green and red clips to con-
nect to the phone line and ground.
To identify the wires, if using the floating method, momen-
tarily short the target wires together to active True Trace,
and listen for the cadence change. If it changes, you’ve found
the target pair. If no change occurs, keep searching.
To identify the wires, if using the grounded method, mo-
mentarily short the target wire to ground to active True Trace,
and listen for the cadence change. If it changes, you’ve found
the target wire. If no change occurs, keep searching. This
will not work if a fake ground is being used. An actual ground
is required to activate True Trace.
An “Open Fault” may involve either one or both wires of a
telephone wire pair. Finding the open will only work if there
are no other faults (like a short to earth ground) in the pair.
If the pair is “live”, disconnect the pair from the incoming
telephone line before trying to locate the open. Short the
wires together at the far end and connect the shorted wires
to a good earth ground (a fake ground may not work well).
At the other end of the wires, connect one of the clips of the
FOX 2 to a good earth ground. Experimentally connect the
