Stan, OK I get it now! I think I will try it at 18.9 Volts and see what happens. Here is another scenario....
I am using the U terminal and the D terminal on the KW transformer to get 18.9 Volts to the switches.
The U terminal and the C terminal give me 6.3Volts.
The C terminal and the D terminal give me 12.2Volts
Would the 12.2 volt setting be better to preserve the LED's?
If yes....Where would I put the old wires that were on the U terminal? On the C or the D? or doesn't it matter?
Also, would the 12.2 volts be enough to effectively throw the switches completely?
I know thats a lot of questions, sorry, but my electrical knowledge is limited, but I am trying to learn!
The block signals are coming along great...got them painted, now waiting for the Led's to arrive, then drill holes and hook up to new electrical schematic.
Tomorrow, I will run the extra wire through the walls and up to the ceiling to reach the switches. Then a terminal block to send the juice to the 6 switches.
Thanks for all the support....I couldn't do it without you!!!
