Tracing Energized Wires
1. Connect the Alligator Clip Cord set to the T-4000.
2. Make sure the voltage does not exceed the T-4000 rating.
3. Connect one alligator clip to the hot wire and the other to a separate ground. At a
receptacle, use the C2901 Pigtail to access the hot wire. Use the 25-FT ground test
lead to ground the T-4000. (Make the connection as shown in Figure11)
4. Turn ON the R-4000.
5. Select ‘SHORT’ mode.
6. Starting with Low sensitivity setting, circle the area with the R-4000 to locate the
path of the wire.
Tracing Unenergized Lines and Finding Shorts
If the wire you wish to trace is part of a complete circuit, or can be made into a com-
plete circuit easily, use the following procedure. If it is not part of a complete circuit
then use the “Finding Opens” procedure on page 13.
Follow the following procedure:
A) Connect the alligator clip cord set to T-4000.
B) Attach one alligator clip to the wire you wish to trace and the other one to ground.
C) Turn ON the T-4000.
D) Select the appropriate signal level.
E) Turn ON the R-4000.
F) Select the appropriate mode and sensitivity.
G) Trace the wire.
Locating Individual Wires in a Bundle
Energized and Unenergized Lines
1. Attach alligator clip cord set to the T-4000.
2. Verify that the voltage on the line does not exceed the T-4000 rating.
3. Connect one alligator clip to the wire you wish to identify and the other to a separate
ground using the 25’ ground test lead.
4. Turn the R-4000 ON and select ‘Low” sensitivity.
5. Set mode to “SHORT”.
6. At the bundle, pull each individual wire away from the other wires as far as possible.
7. Use the R-4000 to detect the proper wire.
8. The strongest signal indicates the proper wire (Refer to Figure 18)
