Tonight’s Cockup:

1. Wired T415;416;417 white side. Red already wired and attached to Red BUS.
2. Wired the white wires of T416;417 to their BD-20s.
3. Wondered why up to 3 LED lights on the BD-20s lighted up at the same time.
4. After a while I realised that the gaps had been cut in the RED rails – but not in the white.

Solution:

1. Cut gaps in the white rails as well.
2. That should fix the problem and will be a lot easier than re-wiring the Red wires through the BD-20s.

Then carry on with the schedule . . .
