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.
