It is used.  I checked the trucks and cleaned contacts.  I'm getting power to pcboard from rails.  I think I'll go on the assumption the board is fried.  I'm going to try wiring cheap mobile decoder directly, bypassing board to see if it will run. 
Is the Bachmann FT, with DCC OnBoard a good enough running engine to warrant the investment in a Soundtraxx Tsunami decoder?

The PCB01 board is integral with the dcc decoder.  There are only the red/black wires coming from the trucks to the board, then a brown/gray wires to motor from board.  All are soldered wires.  Don't know how I could bypass dcc for dc control?  Is there a plug-n-play dcc sound decoder made for this engine?

I recently acquired a Bachmann FT-A DCC On-Board locomotive with a PCB01-B board.  I have a Digitrax system and when I put the locomotive on powered track, I get no response from the locomotive.  I'm getting 14+ volts to the red/black wire solder joints on the pcb from both trucks, but that's it.   No light to the LED.  What can I do from here to troubleshoot?
