Good evening everyone
Well, the predicted poor weather never materialised, instead we had some sunshine. But I decided that I would stay with my original plan and add the dropper wires to the 3 way point. Before heading out though, I wrote an operating schedule the point, as well as a ‘truth table’ to assist in planning the switching of the polarity of the 3 crossing vees. Once I’d drawn it up and double checked it, I realised I could make even simpler.
2 of the vees (circled in yellow and green) can remain connected as if they were one, this is now circled in red. The yellow and green will be the same polarity, when diverting left or going straight ahead. When diverting right, the polarity of the green and blue will be the same, the polarity of the yellow doesn’t matter, so that too could be the same as the green. So, that just meant I only needed to solder on 2 drop wires, instead of 3. Hopefully, the photo below hopefully explains it a bit more.

After dinner, I phoned the surgery to get the results of last week’s blood test, unfortunately my PSA has risen again, it now stands at 17.8, instead of 14.76. At this rate, when I my next PSA test in July, which I’m sure will take me over the ‘20’ threshold set by The Christie, I’ll have my medication admended and be put on an extra drug.
