I purchased some black telephone line from Home Depot (or wherever), a bunch of RJ11 connectors and the crimping tool so I can do my own custom length cables for my detectors. However, I find this cable is so frail that it tends to break and/or lose connectivity after a while. The stuff I purchased has only a couple of copper strands and has a soft fibre twisted around it. The stuff is just too delicate and is a PIA to solder and work with - - it's driving me crazy.
The problem is not with the crimped connection at the RJ11, but at the other end where I go into the fuse panel with these tiny little wires.
Can anyone make a suggestion on a more durable arrangement?
