I have a Lionel Pennsylvania non-powered B unit, 6-24510 that I just purchased. When it arrived, I heard a rattling noise from within. Upon inspection, I found a loose circuit board roaming around inside the shell. The part number on the board is SDK3103. There are three distinct possibilities to re-connect this board. On one side of the fixed board there are two possibilities, and on the opposite of the fixed board there is only one possibility. Each connection possibility has 12 sets of stacked pins, for a total of 24 gold pins. One of the connect to groups is labeled RADIO, one is labeled SOUND, and one is labeled POWER. The RADIO connect group is on one side of the fixed board, and the SOUND and POWER connect to groups are on the opposite of the fixed board.
Does anyone have any idea which set of pins to connect to?
