Just so you know if you don't already TKE has prints for Dover elevators. TKE will only sell the prints to the customer.

World Electronics sells and repairs these boards.

So looking a the card rack it appears the card rack has the follow boards;
Power
Door
Car
Top & Bottom
And an Intermediate board for each floor other than the top & bottom floor.

There are test points but without the proper prints its hard to diagnose. Can you ask your supervisor to speak with the building owner.
