I opened the case of my AT2004 today and noticed that one of the cables had broken. Thought I would start here to see where and how I can get a replacement. See images below

Thanks in advance.

Check with www.LicensedElectrician.com.
I have had excellent service and advice from them, for my At-4001 set.

I think you are looking for the Amprobe C2901 cordset.

Locally I have bought suitable cables with the covered plug-ends from Johnstone (HVAC supplier) since they handle multi-meters.
I have also used our local Electronic supply house for special end connectors
(sometimes depends on who you know).

I have also bought extra cables and cut them in the middle,
then re-soldered them to make male-male and female-female cords,
with shrink tubing over the joint.
Something with a 600V rating !
 
Seems to be a common issue with those leads, I soldered mine a couple times.

After that I gave up and just use the leads from one of my DMMs.

17,
Well, that gave me a tingly feeling.
I was using the AT-4001 signal tracer,
had one of the transmitter leads strung out 25' to an outside water line,
had a live signal going out.

When I bumped the cable,
the alligator clip popped off and drew sparks. :confused:
This unit works very well, but I was surprised that it drew sparks.
This sort of puzzle interests me.
Now I am curious about what kind of circuitry is inside.

My DataComm signal tracer system never did that,
or at least I have not set it up this way and seen this activity.
 
My understanding is that the Amprobe unit places a pulsing current on the circuit conductors. That is why you can only trace the signal between the sender unit and the source.

iWire,
Sounds about right to me.
On a hot circuit,
this would be a Current Pulse mode of tracing.

In tracing a dead circuit,
I connect one side of the transmitter into the black wire,
and run the other transmitter line out to a water pipe ground.
This time, the signal ticks can be traced everywhere on that wire.
This would be a Voltage Pulse mode of tracing.

So, now I need to experiment on tracing a hot circuit,
going away from the AC source.

Will the fun never stop!
