I appreciate that this will of course vary from manufacturer to
manufacturer, but in general terms can someone give the approximate
voltage? I'm curious because I'm getting a "glow" from the outer
metal casing of a SCART lead connector on several pieces of
equipment.
I think you're right to be concerned. Can't tell where you are,
whether you have safety grounds on the power plugs etc.
I have zero experience with SCART, but pinouts.ru claims that
the shield is chassis ground. The whole idea of a safety ground
on the power system is to NOT have voltage on the shield/chassis.
I'd borrow an actual voltmeter and measure from the sheild to actual
ground. Measuring to the power system safety ground may not help if that's the thing that's compromised. Unplug equipment until the voltage
goes away. Then address the problem for a specific piece of equipment.
Random remote conjecture from the web is no substitute for actual measurements.
I've had the pee, literally, shocked out of me when the safety ground in the house wiring went open. On a related note, I've also seen high
leakage current when a cat decided to take a pee on the equipment.
