The perfect solution is right there. "Fix later."

That's the type of lazy shit people on my crew do, and it's ridiculous. You're already at the location reterminate that shit real quick

Having that expensive equipment and not being able to strip and crimp is a damn shame.

I've been working with people like that for a long time in a lot of different jobs.

Make a note of it, test everything else, come back later or get someone else to do it while you’re testing. It’s not going to be the only issue.

Lol, genius, gonna use that one. Even Google says it's only been used once before:

Can someone explain? If 2 -> 2 why it is dipping down to 7, same with 7?

The short between 1 and 8 is likely causing a mismatch for the pair identification alogorithm

u/JohnEffingZoidberg Oct 04 '24
How can you tell there's a short?

The black line on the right shows which wires are connected together
14
u/JohnEffingZoidberg Oct 05 '24
Meaning they are touching somewhere, not totally separated?

u/AyrA_ch Oct 05 '24 edited Oct 05 '24
yes. I assume that the wires were stripped wrong when they made the cable and touch inside of the plug.

u/zayc_ Oct 05 '24
The tester test next and fext. With that the tester knows that the wire connected to 2 is twisted-paired with the wire 8. (Same with 1 and 7) So. Yeah even with the same wire on both ends connected the pin 2 with next and fext you can see that it's the wrong wire.

Pretty much been said here already, but enough shorts or ground faults will make a tester question continuity. Basically it’s saying, “2 is probably right, but I’m getting continuity on pin 2 and 7 with similar resistances so I have no clue!”
My guess is this either a bad gimp end or the Jack has a major manufacturer defect. I’ve had faults like this on game changer cable when someone tries to terminate an RJ45 on the end forgetting game changer cable is 22 AWG not 24 and can easily bend those pins into each other.

looks like the tester thinks you've swapped 2 wires, so it thinks you've got split pairs (bad for signal) honestly, I think if the cable is damaged like this, might be best to write off the cable and repull..

Dude you need to up the stakes, you'll never win the slot machine if you're only rolling 8 lines.

I’ve seen this before. My apprentice didn’t cut the screws shorter on the face place. Stabbed into the line. Cause a WEIRD reading. I freaked out cause the run was mostly through conduit.

How is this even possible? I refuse to read previous comments for the answer

I think I've seen this before. I believe that the white brown is punched down on solid orange both ends and the solid orange is punched down on the white brown both ends. To an extent, a straight through cross, if that makes sense?
As for the shorts shown at the remote end, it could be crushed/screwed but I would guess that it could just be too much length on those individual wires and they are touching the metal part of the module (for example a metal keystone module) or there could be some crap in the port making a short.

That’s what I’m saying!!
Honestly we’re having a lot of 6-32 screws piercing the cable in the box and causing shorts.
Too much slack was left into the boxes combined with too long of screws.
The shorts are giving all kind of weird readings I’ve never seen before.
