Showerthought: I've been crimping my RJ31X jacks wrong for ten years.
Was on a service call in Tempe last week. Customer's phone line kept dropping the alarm signal. Saw their old installer used a different crimp pattern. Tried it. Signal strength jumped from 30% to 98% on the panel. My go-to method was crushing the wires. Anyone have a good diagram they trust for the 8-pin jack?

Okay, "crushing the wires" is the key part here. That's exactly what I was doing too, just mashing them flat with the crimper. Are you saying the better method is more about a clean fold and crimp that doesn't deform the whole plastic block? I've got a cheap tool and I bet that's half the problem. What did the different pattern look like, was it just the order of the wires or the actual physical crimp action?

Yeah exactly, the cheap crimper just smashes everything into a sad little metal pancake... it's brutal. The good one I borrowed had a two-step thing, first it folded the metal flap down neatly over the wire, then a second press closed it tight without wrecking the plastic. The pattern was different too, like the teeth that did the crimping were shaped to match the connector, not just a flat surface. Total game changer for getting those wires to actually stay put.

Ten years is a long time to mess it up, but come on, does the crimp pattern really cause that big of a signal jump? Sounds like maybe the old wires were just corroded and reseating them fixed it. A bad crimp usually just fails completely, it doesn't give you a weak signal.
