I just purchased the Morton Salt bldg. I am powering the lights with a 4.5 v dc, 600ma wall-wart. When I have the switch set so all lights and signs stay on, everything works fine.
When I set the switch so the signs go off and on and the salt looks like it pours is when I notice some flicker. When the signs are on, all the lights seem normal, but when the signs cycle off for a few seconds, the remaining lights have a slight flicker until the sign lights up again. Wondering if this is normal operation or if I should return and exchange for another one (if they have one in stock).
