ADCX Rob posted:The track power is supposed to be terminal "U" to the outside rails(lockon clip 2), terminal "A" to the center rail(lockon clip 1).
That leaves you with "D" to the switches at 20 volts, which will snap them very nicely, but will melt the lanterns at that high setting.
Instead, connect the switch power to "B" and adjust to the lowest setting that provides good switch action.
I agree with Rob, who I think explained the wiring better than me.
