I personally would remove the bulbs from the offending rooms , you are picking up now, or proberly will pick up readings through or from the neutrals
Would the permanent live be the red wire with the strapper (link) as this is the only one that lights the neon electrical screwdriver?
Red with Strapper (link) : 24v : 24v
Trouble is, do you really want to trust your electrics to an extra-terrestrial feline?
1) You cannot light a real neon with 24V.
I didn't try the earth wire with the neon.
Tested the screws - no reading. To be sure thou I took the plate off. Again no reading on just the earth wires with the neon.
