Well, the tape on the mains lead might have started the alarm bells ringing, but the full glory isn't revealed until the plug top is removed. Apart from the obligatory 13 A fuse (people use these because they never blow) the green earth wire is disconnected from its terminal and the black neutral wire doesn't even have a fixing screw in its terminal - the wire is just loose. Well, at least the red live wire is properly connected. That's good, isn't it?
