I just bought a new bachman 2-10-4-santa fe steam loco. and tender at a train show item #51204 . in the box is a small plactic bag that contains 2 tiny 3 pronged metal parts no instructions as to their use .can anyone help?
rrtom,
If you wish to unplug the decoder from your locomotive (in the tender), those little prong pieces are bypass plugs that are inserted into the decoder receptacle.
Not always easy to find right away, but there should be a small, square piece of paper in your box that shows how the plugs are inserted into the decoder receptacle.
I run DC, so I use those little plugs. Unfortunately, I have never taken a picture of how they are inserted. A description may not be helpful, but you plug them into the holes in the lower left corner and upper right corner.
Regards,
Jonathan
