I purchased a basket case building - and am re-building and re-finishing the entire structure. It has 3-different circuit boards within the interior, along with a rats nest of wiring. I've isolated two of the circuit boards to two Miller Engineering signs (yet to be tested). The 3rd one appears to be connected to interior building lights, and am wondering if the Miller sign power leads should also be connected. Is this an AC to DC converter board or just a terminal of some kind (and if just a power terminal what are the various circuits on it for)? I suspect the red and white leads shown on the bottom of the board are the leads to be connected to a transformer - but can it be AC or DC power?

Thank you.

Again, based on that website it's likely an LED controller to blink or sequence LEDs- however that specific function of the sequence or "what it does" is specific to the code flashed to the microcontroller chip. So they used one common board- and then programmed them for different functions.

I cannot see in your picture if the orange painted chip has any text on it indicating the program type.

Again, the current series of boards says this- but unknown if that then applies to the older series 100-3

• Input 9-12V AC/DC
• Dimensions 1.70" X 1.70"
• Draws approximately 10mA

I would try a 9V DC battery as a test leaving the LEDs connected to the outputs and see what it does.

No text that I could discern on the orange chip. This is a Railking building and the former owner obviously went for flashy effects with multiple signs and who knows what else, however he did not care for the building, or was rushed to build a layout, that is evident by how he retrofitted it all together, made holes, and wired it. I've thoroughly cleaned the outside walls of the 4-story building...it was at terrible mess, and windows were installed upside down and not flush with frames, clumps of spackle paste slopped on just about everywhere; window acetate missing from about 1/3 of the windows, wind. Next comes the electronics. Even if they don't work, I'll get some warm lights installed and this will be a nice addition to my uptown city.  I have to admit I enjoy working more on buildings than the trains. Thanks again, Vernon.
