I used the S version as it has all the connections needed for a forney loco. I tie the lights and smoke to the 10 volt source and change CV 60 to 160 to reduce the voltage to the lights. Also change CV 114 to 128 for F6 smoke no reduced voltage as the smoke can have 3 heats by changing CV137, 138, 138 plus cv132 to a 72. This gives a wisp at idle (137), smoke at run ((138) and lots of smoke under heavy load, accelerating (139).



There are 3 ways to add bell/whistle sound sensors in LGB engines.
1 For the forney, LGB has a dual sensor that mounts on the rear freight truck. Same unit on Moguls with sound in the tenders.

2 glue reeds in the rear bottom of the motor block
3 get the LGB motor block sensor board with hall effect sensors.


I prefer the 2 glass reeds on the bottom of the motor block, by far the lowest cost method. Note left rail is bell, right rail is horn/whistle.

OK thank you very much.
Why reduce voltage to the lights? My Forney says it is DCC ready so I expect the lights can handle the DCC voltage.

Trust no one (except Dan ha ha!) .... DCC ready means you can easily connect a decoder.... does not guarantee the bulbs won't burn out at higher voltages...


I think the forney headlight was an incandescent bulb.

yeah, you are probably right about that.

Which speaker do you recommend with this 696S?
I see the Visation FRS5 is 5W 8Ohm and (according to my measurements) will just fit in the back. But will the decoder fit in there with a speaker with that large of a magnet?

All LGB moguls and Forneys came with 5 volt (really run at 6.2 volts by LGB) and 5 volt smoke (seuthe 4-7 volt units). LGB runs the smoke 'hot' and the lights 'bright'. My 18 year old mogul still has original smoke and bulbs!!
SO, running smoke at 5 volts will be weak and that is why I use 10 volts with voltage reduction from 10 to simulate 6 volts on bulbs and 3 different voltages on the smoke unit via Zimo programmable pulsed power and I listed the cv's that control this plus the cv to ignore the voltage reduction for smoke as it is taken care of via cv 137-139.
