June 20 Gift from a Friend
This was a gift from a friend. We met on a Model Railroad Forum where he had posted a answer to a question from another Railroader. I had a similar problem and I e-mailed him for more details. We have become good friends and often share our Model Railroad hobby information. He Lives in Ohio and models the Ohio road names as well as the NKP. His favorite locomotive is an EM-1 while mine is a Southern Pacific AC-9. We are both interested in remotoring the older articulateds. I got him curious about the SP engines and he bought a Cab Forward off E-Bay and later an Akane SP AC-9. His brother had a Cab Forward and it was given to my friend after his brother died so he didn't want to ding that one installing a new can motor so he bought the E-Bay engine to experiment with. He has since decided not to remotor either of the Cab Forwards so he sent me his E-Bay prize as a gift.
It was very close to being a basket case locomotive. The snow blade was with it as was the cab roof, the chassis was intact which was a surprise. The front coupler box was dinged and the coupler was missing along with the marker lights, horn, whistle and the leading truck.
I purchased a casting kit from Micro-Mark last year to make missing and broken Rivarossi parts as I have a large fleet of Cab Forwards.
The coupler, horn and both marker lights in the picture above are replacement castings made from my molds. I also added the glass in the windows and changed the number from 4272 to 4270. I had a new leading truck assembly in stock.
The Rivarossi motor was working very good so I didn't replace it. The picture above shows the whistle casting in place and the added wire from below the Monkey Deck to the tender for the rear light. The left rail power is original Rivarossi connecting through the drawbar.
The tender that came with the engine was a Y6B coal tender, I bought this oil tender off E-Bay earlier. I installed a white LED in the rear light housing. This locomotive is now a beautiful showpiece as well as a very good runner.

June 2nd Almost finished
This Cab Forward has the Tomar Adlake Marker Lights installed and working. It also has a white LED for a headlight that is controlled by the DCC decoder in the tender. I used 4 pin Deans Micro Plugs between the boiler and chassis for the lighting power connectors in all my Cab Forwards for compatibility.
The DCC installation in this Cab Forward is finished except for touch-up painting and gluing the Monkey Deck back.
This is a closeup of 4294 showing the wiring from the DCC connector to the Faulhaber 2224SR motor and the Deans 4 pin connector for the marker lights and headlight. I used Goop glue to hold the motor in place.

June 2nd Below the Monkey Deck
The Rivarossi Cab Forwards have a hole below the Monkey Deck that is just slightly smaller than the NMRA 8 pin DCC connector. I enlarged it a bit for the connector to drop in. It is the perfect location for the pig-tail from the tender to easily plug in. The Monkey Deck platform can be removed without damage using an X-ACTO knife and being very careful.
This is the rear view of my Cab Forward #4294 with the 8 pin NMRA DCC connector mounted in the hole below the Monkey Deck. I will paint the wires flat black between the cylinders and steam chest so they are not seen then I will glue the Monkey Deck platform back in place.
The Monkey Deck is glued back with the DCC connector in Place.

June 2, 2010 Cab Forward DCC Wiring Diagrams
This is my DCC wiring diagram for my five Rivarossi AC-12 Cab Forwards. They are a newer version that came from the factory with both right and left rail power pickup in the locomotive. My five older AC-10 & 11 Cab forwards have single rail power pickup, right rail in the locomotive and left rail in the tender. I replaced all my Rivarossi tender trucks with brass Buckeye trucks for more reliable twelve wheel power pickup.
This works out very good, the new Faulhaber Neodymium Magnet Motors are very powerful and they draw less than 500 ma. from the decoder under full load.
This is my diagram of the older Rivarossi AC-10 & AC-11 with tender power pickup.

Important information:
First: For those that are using the Rivarossi motor you must isolate the motor wiring from the frame for DCC operation!
Second: The Rivarossi motor will draw in access of one Amp easily under load, make sure that your DCC decoder will handle 1� Amps!
