D .6.9 Completing the Installation
Checking W iring Continuity
Open the tool, and remove the connector and cable. Locate pins 1, 2,
and 3 of the connector as shown in Figure 96.
Using an ohmmeter set to a lowresistance range, verify that direct
continuity (zero ohms) exists between each white wire and pin 3. Verify
direct continuity between each blue or black wire and pin 2. Verify
direct continuity between each bare drain wire and pin 1.
If an improper connection has been made, and you have already
installed one or both of the connectors at the two ends of the network
cable, it is possible to read either 60 or 120 ohms resistance between a
blue or black or white wire and its pin. Make sure you have direct
continuity (zero ohms) between each wire and its proper pin.
Verify that no continuity (an open circuit) exists between each white
wire and each drain wire. Verify that no continuity exists between each
blue or black wire and each drain wire.

Trim the W ires
If continuity is normal, trim the excess lengths of wire so that they are
flush with the side of the connector. If continuity is not normal, repeat
the installation procedure with a new connector.
