Tone out speaker wires.
You can determine the positive wire by looking at the led.
This will tone down and turn off the speaker volume.
Connect each end of the single wire to the positive and negative leads of the multimeter.

The tone generator cable tester is the main testing unit and is used to test cable continuity for coaxial cables rj45 and rj11 cables and for individual wires using the attached alligator clips.
It s an inexpensive tool that will cost you around 50 80 and save you multiples of that amount in time and frustration.
Step 6 dc circuit.
If there is an unbroken circuit through the speaker there will be a continuous tone output from the multimeter and or the meter will not read ol open.
To test the continuity of the wires themselves and both ends of a single wire and test the continuity.
Step 5 speaker.
So if you ever find yourself trying to trace out speaker wires or data wires use an analog tone generator and probe.
Take a couple of wires and establish contact with the dc circuit.
If your wire has light colored insulation this stripe or dash may be dark.
A detachable remote terminator is used for rj45 and rj11 cables to provide the continuity link at the remote end of the cable.
