Chuck and others, would it be ok to hook up say 4, 5, even 6 Menards buildings to a terminal strip that was powered by one of the Menards 4.5 VDC adaptors? The # of buildings would be determined by measuring the voltage load as I added buildings to the terminal strip, that is until the voltage was around 4.5 VDC. I guess I'd also have to measure the amp load, right, as it shouldn't exceed the adaptors output?
I'd follow your advice on using a regulated VDC supply but have no clue as to what to buy let alone install it.
I just read on the main forum another poster who reported failures in his Menards building lights.
