gunrunnerjohn posted:Important point. Was the smoke unit plugged into track power with the PS/3 board connected? In other words, did they not disconnect the track power connection and power it up with the PS/3 wiring connected? If so, they could have certainly damaged parts on the PS/3 board!
If they just didn't cut the traces and powered up just the PS/3 board, I suspect it would have done much less damage.
I've attached a picture of the type smoke unit used in the locomotive. In the picture (from MTH's instructions) the trace that was supposed to be cut was not. The smoke unit was wired correctly except for the cut not being made and then the smoke unit was turned on. There's a big note about that damaging the board in the instructions if the cut is not made to the trace...… Is the damage that caused repairable or is the board trashed?
