MANARDS MELROSE PARK TRAIN STATION

It is just as possible the power supply needs to be powered fully first. I have 2 recharge wallwarts (repurposed) that need the item to be plugged in after the ac is applied to the wart.

Probe the wart alone (no load) for voltage . Then with load, then after unplugging from ac.    Does waiting a few min./hours allow for a power up via ac?  (Im thinking maybe a capacitor being "full" , the decreased load may not be enough for the supply to turn on. Time may give it opportunity to empty itself ...?

Most led boards just modify the power so the led can handle it without cooking... i.e., resistors mostly, maybe diodes & caps, just maybe a voltage regulator and/or opto isolator, but the latter, not real common.  Considering the price, I doubt the boards are complex enough to "demand" anything but proper voltage.

I have always noticed a slight delay when I first power up all my Menards accessories but they always come on. 

Are you using the recommended 4.5 volt power supply? Do you have another 4.5 volt power supply to try it on?

Yes I'm using the recommended 4.5 volt power supply.  I have another one for the Starbucks I bought from Menards and the Melrose does not work properly on either power supply.  I think the Power supply is good but there is something wrong with the station circuitry.

I have the Menards starbucks and it come on with power.  I have wanted more then 10 minutes with the train station and it does not come on.

It appears that the power supply needs to be power first, then the station for it to light.  That will not work for me, when I apply power to my train layout all my lights come on, even the Starbucks Menards with LED lights and the same power supply.  I have email Menard asking for a replacement or credit.  Waiting to hear.  Thank you all.
