It's not hard to fix this problem by hard wiring the motor contact to the board. I use scraps of orange and gray wire left from wired decoder installations. It does not matter which color wire is used as long as the wire from the bottom brush goes to the forward slot and the wire from the upper brush goes to the rear slot just as the tabs would if they lined up properly.
For the top motor brush first remove the brush holder and take the tab off. Then solder the other wire to it. When cooled re-install holder with spring and brush into motor body.
A nice thing about this decoder board is that is has big solder pads to easily connect extra lighting functions.
In some future post I will show some ways to use these additional functions.
