RRMAN, I see your point, seems hard to fathom that each building would draw 2 amps, though, given they're LEDs, but that's what the power adaptors specify. On the little transformer at 5.5 VA - I thought volts x amps = watts? Good point on the buildings that have the Miller engineering signs, am not sure which buildings they are, though.
As I was laying in bed last night I realized something I overlooked - the Menards buildings all have different #'s of LEDs, some only have 1 or 2, while the Power plant must have close to 20. The 3 buildings I've been measuring with meter only have 1 or 2 each (and the 3 buildings that the original guy who said his burned out were all minimal lights as well). Wouldn't this then be the reason why the voltage load is still high in my measurements? Assuming I am correct, could I cut the main feed from the power adaptor (see photo) and send it to a small terminal strip (hot and common). Then, cut the 3 feeder plugs (and remove the plastic junction) and re-connect the 3 feed plugs + additional feed plugs (that I'd have to cannibalize from other adaptors) to the terminal strip and to as many buildings as it takes until the load comes closer to 4.5 volts? These are wired in parallel in original state, right? Or, would this mess up the amperage output of the adaptor? Does this make sense? I'd be cutting the wires at the location the pens in the photo show - and removing the junction - it'd be replaced with a terminal strip that could output additional plugs to 4, 5, or x # of buildings needed to bring voltage to 4.5 VDC.
