TAS Smoke board pinout

The EOB board generates the chuff, check the EOB instruction manual.  Here's a link to the manual from the TMCC documentation thread.

Actually I was in error in my request. It's the J3 pinout I need to know. I have a couple of these units and the way the regulator is wired up seems to differ. If I'm reading the manual correctly the orientation on the mother board from left to right is: gnd, smoke, chuff, fan. Where does the chuff wire hook up to?  

I have these, but I never saw them wired, so if you find out anything, I'd like to know.   I'd also like to see how they're wired in the diesel configuration.  I have the matching smoke units, they have three terminals that are presumably for power and control inputs, they came out of diesel locomotives.  They don't exactly match the Turbo-Smoke documentation, I'm guessing these were OEM models that didn't have the steam/diesel jumper described in the Turbo-Smoke document.  Did you look at the Turbo-Smoke Documentation?  Is this the smoke unit you have?

I also believe OEM could not do the same because of patent issue.  G

That would be my guess, but it would only be a guess.  I'm considering these as diesel smoke units.  If I want to use them with steam, I could use the Super-Chuffer with them to control the fan motor, job done.

I believe what you have there is a TAS Puff n Chuff board or some variant but I could be wrong. I used a few of these back when I ran smoke but sadly I don't have any around anymore. 

They came out of 3rd Rail diesels if that's any help.

I have seen them in Atlas.  I did hear from the source the OEM ones did not have the capability.  G

Makes sense.  I probably should connect one up and see what it does when I ground the 3rd wire.

Here is the smoke units I have in question. They are TAS units although not turbo-smokes. I guessing if I use these in a steamer I just splice the purple and gray wires in the harness to route back the the tender. As GRJ points out the chuff is generated by the EOB board and all that is needed is the gnd and smoke connections from the four pin socket on the mother board. The second to last pic I believe is a turbo unit although this doesn't look like the same unit in the TAS instructions. In the Last pic, that smoke unit (which looks similar GRJ) is in an EOB equipped Atlas Erie Built.

The last one looks a lot like mine, except with unused component locations.  I think the one may be the turbo unit.  The others look like clones of the Lionel, I wonder if those little boards provide the extra functionality with them.  If you get one of the top ones working, let us know how you wired it.

It does have the thermistor for shutting off element if temp rise to high.  G

Mine all have the thermistor as well.
