I have problem with my ceiling light switches. the bedroom, living room, kithcen and bathroom lights will only switch on when the hallway ceiling light is swichted on. I have tried swapping somw wires around, but to no avail. The switches are mixed - one 3 gang with 4 +2 wires, two 1 gang with 3 wires, and one 1 gang with 4 red and one yellow wire (?). Can anyone point me in the right direction without me paying a fortune for an electrican? many thanks.
