• The FOX 2’s tracer tone will pass through any electrical
circuitry connected to the target wire(s). Hence, to
identify a specific wire, it will be necessary to disconnect
all loads and circuitry from the wire. This includes
switches, capacitors, resistors, coils, transformers, lights,
motors, etc.
• The FOX 2 tracer tone can be shorted out by any loads on
the target wire. All loads must be disconnected from the
target wire.
Crosstalk and TrueTrace:
Crosstalk is the bleeding of the tracer tone from the target
wire onto adjacent wires. This often happens in multiwire
cables, or in cable harnesses where many wires are bundled
together in close proximity to each other. A tracer tone ap-
plied to a target wire or wires may crosstalk onto adjacent
wires. Some wires/cables are constructed to reduce the
crosstalk, but other wire/cables crosstalk readily. So much
crosstalk can occur that the tracer tone on the adjacent wires
can be almost as large as the original tone on the target
wire. This can make it difficult to identify the target wire with
the HOUND or HOUND 2 (Receiver). The traditional method
of trying to determine if the tone being received is the origi-
nal tone, or is crosstalk, is to short out the wires with the
tone where the HOUND is being used. If shorting the wires
only reduces the tone’s level, but does not completely kill it,
then the shorted wires have crosstalk on them, and are not
the target wires. If shorting the wires completely kills the
tone, then its likely that the wires are the target wires. Un-
fortunately, this is not 100% effective. The FOX 2 uses
