I think that was very naughty of him, leshby. Let's try to make it work without unauthorised diodes connecting various bits. If the square diode has its minus terminal connected to the upstream part of wire 15, and its plus terminal connected to the downstream part of wire 15, with its two AC terminals not connected to anything, it should act like a normal diode and we might get some sense out of this. Remind me to write a whole new thread on tenants' improvements some time.

Can you tell me what happens when you make Tests 1, 2 and 3 with wire 6 connected to the green wire at one end please? Test 1 is just grounding the other end of wire 6.
