Neutral-Earth Voltage 120V

The Old "Drummond" testers had some advantage if used with care.

Additionally the old homemade Plugtop three resistors and two neons might have some merit but not the most foolproof of things.

Equally I'll not describe a number of my techniques but I too have loop Z kit.

As OP has 120V on fitting earths, that will show on a LED screwdriver with ease just by touching any exposed metal/screw attatched to it and that may be easier than getting to the fitting, possibly unscrewing it and attatching wires.

I'm not trying to negate any other testing technique.

However I'd still check for V before Ω... see https://www.diynot.com/diy/threads/drain-on-electric-power-supply.482573/#post-3907705 post #7 or https://www.diynot.com/diy/threads/a-real-moan-tonight.552183/ for such an examples why

Excellent idea, so simple, can't think why I did not think about it.
