I have an MTH Op Dispatch board, 30-9022, the first release. The man returns to his stationary position, but the board does not stop flipping. I'm suspecting an internal switch is not operating correctly. So 2 questions: 1. Does someone have an exploded diagram and parts list for this? And 2. How does one take the thing apart? I pulled the 2 screws in the corners of the tan structure, but the top does not budge. What else do I need to do?

Looks like two people have asked about this accessory with no responses. So I'm guessing it's not too popular an accessory. 
This current thread and this one: MTH #334 Dispatch Board problem | O Gauge Railroading On Line Forum (ogaugerr.com)
I have come upon one of these in my recent auction "box of stuff" acquisition. It's in bad shape, but when I apply power (wired correctly, or simply with an inline switch to power), I get the lights on and all the boards rotating (changing train info) as long as I depress the button.
I was wondering if this item might allow me to press the button, get a momentary response just long enough to move the board one position: DC12V Adjustable Infinite Cycle Loop Delay Timer Time Relay Switch ON OFF Module | eBay ?
Thanks, as always, for any sage advice!
Just checking in with any electronics wizards among us if they think this inexpensive device might be useful for turning the operating dispatch board sign (in absence of other on-board circuitry working properly)?
