Stan,
Just wanted to thank you again.  I tried the Rectifier and as you said everything works as it should.  I think Bachmann should have mentioned this in the manuals.  At any rate, thanks again.

Stan,

Thank you very much for your response.  I have spent all weekend trying to get this right.  I guess it make sense. I wish Bachmann would have explained it a little better. 

If I may I'd like to ask a couple of questions to clarify:

I use  NCE decoders D408SR  and I think they just have  (2) blue common  output and the  9 functions (-) and no other connections other than the motor and track connections.   I guessing I need the rectifier.

Are there any specs on the rectifier to look for, or any type ?

When you say connect the AC side of the rectifier to (J1-1 and J1-12), do I use soldierable connections on the end of the board ?

And as for the the " rectifier + to the locomotive + and the rectifier – to the locomotive -"   is that the wires on DCC daughter board labeled Train Bus (+) and Train Bus (-)  or Loco ground and Loco positive. 

I'm thinking its the Bus (+) and (-) because the Loco positive is the blue wire connected to the Decoder. 

As you can see I'm a novice at this, and I appreciate your help very much.

Willy,
Thats a great solution.  I thought of it but was afraid to try it.  In addition to getting the firebox and cab light, do you get the smoke to work on the DC setting.   What happens to the front and rear leds?

I spent over an hour on the phone with Rodney from Bachmann.  He was very helpful, but since it is so new he was going to experiment with it and let me know what he came up with.

I did get the firebox and cab to work DCC, but only at idle, when the throttle is moved the firebox freezes lit with no flicker. 

I am going to either live with a frozen ficker and wire the front and rear leds directly to the decoder with a 1K resistor,  or try your solution if the lights and smoke will work by switching them from the bachmann switches.

Thanks for your response.  I wonder if the Plug and Play guys are having any of these issues.

I wired in an NCE decoder to my 2-6-6-2 using the supplied Bachmann DCC board insert.  The Loco runs great on DCC, but the Front and Rear LEDs won't work.  I hooked the decoder to the White, Yellow and Blue for common just like my other Bachmann's but no output.  Also while the DCC board is inserted the firebox and cab light won't work on any of the settings of their switch.  I tried another Decoder that I know works and same result.

When the DC board is inserted everything works as it should.   It seems that the problem is with the DCC insert board...

Has anyone used the Bachmann DCC wiring board to wire in a Decoder. 

Thanks for any suggestions.
