I made a bunch of 1ft cables for my pedal board using an old (but decent) cable and Neutrik NP2RX connectors. A few of them work fine and read only <0.1ohm tip to tip & shield to shield. Likewise, they read infinite ohm tip to sleeve. The problem cables read 1kohms +-500 tip to sleeve. Not good. They all look completely fine and just like the cables that work. I know how (love) to solder and I did a pretty good job and took my time using a silver bearing rosin core solder and a 30w soldering pencil. The old cable has what I believe to be conductive pvc in it. It goes: inner wire -> conductive pvc? -> insulator -> shield/ground wire -> conductive pvc -> outer insulator. EDIT: I believe I have it wrong. It is inner wire -> insulator -> conductive pvc -> shield -> insulator -> conductive pvc. and so having that melted onto the core wire or touching the pin would have effectively shorted the pin to the shield. Would explain everything. Just need to peel that back a bit and resolder. Tried searching but I could not find anything exactly like this... First image is a good cable, second is one of the culprits. I melted the pvc/insulator a bit when getting the iron in there but I couldn't imagine that would be the problem...All of the connectors basically look exactly like the good one.
