Default Confused 120v & 240v Wiring - Please Help

When the LOUNGE SWITCH is OFF and the OUTDOOR SWITCH is ON, there is
120v at the OUTDOOR SWITCH, and 120v at the LOUNGE LIGHT & SWITCH!!!!!
i.e both bulbs are at half power, even though the lounge switch is
OFF



It sounds as though the outside light has been tapped off the live side of
the lounge circuit but not been issued with a neutral connection and is more
than likely running to earth through the filament of the lamp in the outside
light. The 120 volts is being back fed through either the earth or the
live.


I've actually seen this done more than once, and the reason behind it
being that it is a reminder that the outside light is still on when the
lounge light is turned off to go to bed!!

I kid not, and yes the people involved were misers
