Well, I had to fix a circuit...original box had too short of wire that broke off on me. I installed a junction box in the attic to extend with romex. Attached romex ground to the box with a grounding screw, used bx connector. Tightened locknut pretty darn tight.
It read 10 ohms from neutral to ground. Neutral connection is solid...so I'm thinking its the bx jacket. There is no box in between this run...so it should be a straight shot to the panel. I checked all the bx connections at the panel, pretty tight. I tightened them for luck...
Another room has the same issue, or at least it "had". It has its own 14/2 bx to the panel. It used to read 40 ohms from neutral to ground! Now it reads 1.5-3 ohms to ground. Maybe the tightening had an effect...but I couldn't even tighten the screws a hair, they were that tight already.
Is it possible that this is just bad bx, like a broken bonding strip? Or do you think there is a junction hidden somewhere?
*maybe the bonding strip was old and cracked when I was up in the attic?
