I have a Williams New York Central Hudson #5205 whose smoke unit has quit working after a period of it working only intermittently. Is it possible to replace it or fix it? If it is possible, is this something that I could do myself or would I have to send it off to someone?

Original Post

It's a two wire Seuthe smoke generator.  I think it's a replacement part, no repairs if you verify that it has power.

Unfortunately, they either work or they do not- nothing serviceable. Fortunately, it pulls out of the stack easily and unplugs from a convenient circuit board you can access through the smokebox.

While I was finding out which smoke unit the engine has, I discovered that it is wired directly to a circuit board at the same spots the headlight is connected. 

The engine has had ERR TMCC installed, and, ever since, the headlight has worked intermittently.  I am now wondering if part of the problem has been that the smoke unit has not been getting power all the time.

Is there a way to find out why the power has not been constant on the headlight/smoke unit?

I have another engine (Lionel), similarly converted to TMCC by ERR, that has the same headlight problem.  Any suggestions as to what might be causing it?

I sent my Williams ATSF scale Hudson to Gunrunnerjohn to have him install a fan driven model. He did a great job. However, maybe too good. You might ask him to set it at a  smoke level you would most desire.

We have just the ticket for you Jeff!   Is this the level of smoke you are looking for?

Two things to consider.

1. Turning the smoke on, after a brief one or two second period, the power goes to half wave. That's half of what the smoke unit used to see.

2. The Seuthe smoke unit driver transistor/regulator has a heat sink mounted on it. I have seen the heat sinks come loose. That would shut the smoke unit down when the transistor/regulator overheats.
