FA-1 Re-Wiring Diagrams and Instructions

Beginning in 2001, new locomotive models started arriving with a plug and play PC board (PCB-1).  The board is designed to allow easy installation of either a DCC (Digital Command Control) decoder or RCC (Radio Command Control) receiver.  

Some FA-1's with the new "Plug and Play" (PCB-1) PC Boards manufactured in late 2001 and early 2002 may have improper wiring.  The wires from the motor blocks may have been improperly installed in the plugs on the PCB-2 "Bus Board". The wires from the motor blocks are color coded.  Inspect the wires at the plug on the PCB-2.  If the order of the wires is RED, BLUE, BLACK, WHITE, the wiring is improper.  The proper order of wires from the motor blocks should be BLACK, WHITE, BLUE, RED. This is easily corrected by unplugging the motor block plugs from the PCB-2, removing the wires from the plugs, and reinstalling the wires in the proper order.  Then plug the plugs back into the PCB-2.

The following diagrams illustrate how to re-wire the PCB-2 "Bus Board".

To remove wires from plugs:  Use a large needle or a nail to push down on the wire tab in the plug.  Pull the wire up and out of the plug.  Reinstall the wire by pushing the wire down into the plug.
