Thanks for providing the images in the 01/08/2008 post - but, even more critical are the images for the 01/09/2008 post for disassembly of the Forney. Any chance you can retrieve those as well?
Roger, I'll try ARGGGGGG! The problem is, some of the broken images are not images at all! They are instead "INCLUDED" html files. Those were common modules that explained procedures that were common to all my Forney installs. The thing is, I have seven Forneys, I installed different decoders and sound cards in each of them, including one that used and RCS RC/Battery. I made a page for each one, but I "included" whole sections of code that referenced parts of the installs that were the same across several Forneys. Those included files had internal references to images that no longer reside on either my original site or the one of the two MLS sites. (I had two first class sites cause one would not hold the entire site.)
Bottom line is, I have to edit the rather complex HTML code in this post because it was cut and pasted from the original site while it was still up. Would have been easier if the MLS site had sufvived the upgrade.
So, here goes.... This may take several attempts, so refresh the page if you still see broken links.
OK, I think I got all of them fixed.... WARNING!
Many of the images were click-able and took you to larger views of the same images, I did not check to see if all of those links worked, but at least some of them do.
The two wires going to the back that connect to the rear truck are wires intended for the sound card. They are disconnected when the switch in the cab is set to the "silent" position, which makes no sense at all,
The loco will operate as follows:
DG583 2K2 F0 Headlights F1 smoke Bell F2 Manual Whistle F3 Coupler F4 Crossing Whistle F5 Doppler F6 Drifting Chuff F7 Canyon Chuff F8 cab light F9 Flickering smokebox F10 F11 F12
In addition the motor control switch will work as follows:
[*]0, 1 and 2 = sound off, everything else on. [*]3 = everything on including sound. [/list]
The smoke generator will turn off when the loco is stopped to conserve fluid.
OVERVIEW The instructions that came with the loco include a drawing that is not a lot of help. They only show a partial diagram of a similar board. It is often best to scrap all existing wiring and electronics when installing DCC. However, the Forney analog electronics works quite well and provides a number of benefits: [*]It provides a current limited output for the accessory socket o the rear of the loco. [*]It provides a handy switch in the cab to turn off the sound. [*]It provides connectors for the lights and smoke. [/list]

STEP 1 - Disassembly
Cab Removal [*]Pull the handrail supports out of the boiler shell. Do not pull on the hand rails or the upright of the supports. You can leave the handrails inserted into the front of the cab. [/list]
There are also three plastic pipes inserted into the front of the cab. Gently free them from the holes but it is not necessary to remove them from the boiler.
[*]Remove four screws from the underside of the floor that hold the cab and tender. The two screws that hold the steps no NOT need to be removed. [*]Gently work the cab straight up and away from the boiler. There are two cables (each is to conductor) at the front of the cab that will restrict how far the cab can be removed. These wires will be disconnected in step 1C. For now, just let the cab dangle. [/list]
Figure 1A Cab removal.
Firebox Removal [*]Remove one screw in the center of the ash pan, Remove the ash pan to expose the two screws that hold the firebox to the floor. [*]Remove the firebox by lifting straight up. Use a felt tip permanent marker to mark both the socket and the plug for the cable on the engineers side Now you can unplug the two cables. Set the cab and tender aside for now. [/list]
Figure 1B Firebox Removal
Slide the Boiler Forward to Expose Connector [*]Remove the screws in the center of the air tanks just below the running. [*]Remove the running boards. [*]Remove the two screws near the front of the boiler, then work the smoke box free. [/list]
You will have to tilt the front of the gearbox down to work the smoke box forward. Wires from the headlight and smoke generator will determine how far it will go.
[*].Now side the boiler forward just far enough to expose the ten pin DCC connector near the front edge of the circuit board. [/list]

STEP 2 - Cable Routing.
The motor decoder and sound decoder must be installed in the fuel and water bunker behind the cab.
Three servo cables will be used to extend the 9 of the ten pins on the DCC connector in the rear of the boiler. The tenth pin is not needed. The cables will run to the tank behind the cab.
For this installation I'll be using widely available cables that can be found at most any hobby store that sells Radio/Control airplanes. Servo extension cables come with a male connector on one end and a female connector on the other. I used three 6" extension cables and cut the male ends off.. I also uses a 12" extension cut in half as a programming cable for the Phoenix 2K2 sound card.
There is a wire tunnel that extends from the firebox to the bunker. You will need to route the following through the wire tunnel:
[*]Three servo cables, (three conductors each).
[*]A red/black pair going to the rear truck.
[*]A red/black pair going to the accessory lighting socket.
Decoder Wiring [*]Familiarize yourself with the LGB analog board. Note that the rear light cable and the cab light cable both contain two black wires and are not keyed or distinguishable from each other. [*]To avoid getting them mixed up, use a felt tip marker to mark both the plug and socket for the rear light. It is identified as L1-R
on the right edge of the drawing below. It is located at the very rear edge of the board in the loco. [*]Disconnect the two black cables from LI-R and LI-C. [*]Unscrew the accessory socket from the back of the fuel and water bunker and set the cab and bunker aside. [/list]
[*]Remove the shorting jumper from the ten pin DCC header on the LGB main board. [/list]
[*]Install three 6" RC servo extension cables on the ten pin DCC connector of the LGB main board. Start at the left side of the loco (fireman side) and leave the last pin on the right (engineer side) empty. [/list]
[*]Mark both ends of each cable to identify them. You will not be able to trace the wires once you get the loco partially assembled. [/list]
I numbered them with 1 for the one closest the fireman side and three on the engineers side.
[*]Remove 3 screws from circuit board. Slide the board to the front of the loco to expose the screw wells in the small rear weight. [*]Remove the two screws in the small weight. lift the weight out of the way, and add the three servo cables to the two existing red/black pairs that run under the weight. [/list]
All wires go under the weight between the two plastic weight mounting studs. Make sure to leave some slack so the board can be slid back into place.
[*]Reinstall the weight and tighten the screws. [/list]
FIG NN - main board seated
[*]Spread the wires around rear plastic standoff on underside of the circuit board. [*]Make sure the wires are not caught under plastic standoff or screw. [*]Start the rear screw into the weight. [*]Start the other two circuit board screws into the weight and be sure all three standoffs are seated on the weight, then tighten all three screws. [/list]
[*]Line up all the cables so they are even and only two wires high. [*]Slide the wire tunnel over the wires from the rear in the bunker area until it is seated under the weight [/list]
[*]Make sure all the wires are captured in the tunnel and that the tunnel is resting completely on the cab floor or you will not be able to install the cab and bunker properly. [/list] [*]Cut the female ends off the servo cables so the wires extend one inch past the rear of the bunker floor. [/list] At this point it is a good idea to reassemble the boiler, smoke box, firebox and cab. This will make it easier to handle the loco.
