I just purchased a Williams Scale Alco FA-1 set in Great Northern livery,  used, but if you were to ask me, based on no wheel or roller wear,  these units did not see any track time at all,  However when I unboxed the power unit, a machine screw was at the bottom of the foam .  A little closer inspection suggests that this screw is what I believe, holds the reverse board to the locomotive. I took the shell off and I can see that the reverse board is free to move. The screw can be reinstalled from below the locomotive frame into the board, but there is nothing in the reverse board that it can thread on. Now the reversing board has the Tru Blast board on top and I would have to cut the zip tie off to inspect to see if there is some kind of plastic nut or if the board itself was threaded at one time.  Any ideas before I cut the zip tie what I should look for?  Also there was nothing in between the board and the frame.  I do notice that the board has a clear plastic shield that would keep the bottom of the board contacting the frame and frying it. Should there have also been from the factory, something in between the board and the frame,  maybe a small plastic bushing or a foam pad?  Please share your thoughts and knowledge.

Thanks

Rory

Hello John:

Thanks for the quick reply.  I did notice that the bridge rectifier that is closest to the center of the reverse board does have some threads in that center hole. However this screw, that does fit through the body with no slack but does not thread on, is too small for the threads on the bridge rectifier, and if it were to thread onto this particular rectifier,  it would cause the board to be pretty much half way into the motor. (not physically possible)  In other words, this could not work if the screw was the right size, which is why I am here wondering if this was some kind of defect, or is there some kind of plastic pal nut or something that would be on the other side of the board.

Thanks again John

Rory
