I have an O-gauge Williams Erie Lackawanna PA-1 A-B diesel set from 1993 (AC-13 and AC-15).
I think the reversing board / control board just died.
The board does not use harnesses; it just has 3 wires each going to each of the 2 can motors.
I can send you a picture if necessary.
Does anyone know where I can buy another board?
Sincerely,
George Lurie

The Williams company has a direction control board that can control 2 motors in a locomotive, as well as lock the direction in forward or operate with the Forward / Neutral / Reverse sequence: https://shop.bachmanntrains.com/index.php?main_page=product_info&cPath=491_555&products_id=3771&zenid=54p02bo7pf3epbtb8nmouu0an7.
