Toggle switches

[M.Morren]

Hi Jacques,

The 3 TPST switches are original and working. I have traced all the jumps and found out that they are all over the place (most power comes in on the wrong side. That's why the Tail+Side and Tail+Side+Head only work when the Tail is on). I understand how and why the current config works.
But what I would like to know is, how is the lighting system supposed to work? See the scenarios in my earlier post. Which one of those is correct?
And is there an explanation as to why I hear different things than that I see in the manual? Did they change the config but nog document it in the manuals?

Thanks for your help!
