Hi folks, I work for Tony's Train Exchange in Vermont and have a problem ESU can't seem to solve. I installed a large ESU brand smoke unit (the large one) with the appropriate ESU decoder in a G scale K4 And in all the settings, I still have pitiful smoke output. It is connected properly and I am thinking there is something I'm missing in the settings. Any help appreciated. Thanks. Chris

Now, a Chevi would make a great smoke-unit! :)

Hi Greg, thanks for responding. I have installed an ESU Loksound XL V4 decoder with an ESU 54679 large smoke generator. This is the same decoder and smoke unit used in Sergio Atelier du dcc 's video here on this website.
As far as settings, I followed ESU's instructions to the letter using their programmer, thus I did not directly change cv's per se.
4 wires run from the smoke unit (su) to decoder, black to ground, red to right rail, yellow to Aux 1 and green to Aux 2.

Oh, by the way, your guide to disassemble the ACcucraft K4 Pacific, was invaluable and very appreciated.

This may be a silly question but assuming the CVs are correct what, voltage is your test DCC system putting out? Is it set for smaller scales or the 19-24 V typical of large scale?

The manual does not specify max voltage, but it is for large scale, and I have not found any modern systems that do not handle the 24 volts that is pretty standard in Europe.

But his issues would seem to indicate too low a voltage to the layman. Internally the unit regulates the supply voltage... the manual for the "big" unit, model #54679 is explicit in this sense.

Awesome discussion. I too was concerned about low voltage so I added a booster to the ESU Programmer. And I would run/test the loco on rollers using a 10amp NCE Powerhouse unit.

Also, I get more smoke production in "coast" mode. !?

ESU sent me a file they use on a show locomotive. The settings in that file contradict the manual, but it works much better than initial settings.
