Hello

I have a question ( Greg ): is the smoke unit for this caboose a special unit or did they just add tubing to get smoke into stack.

I will have to post a pic later ( after I take one )

It has two wire power plug, feeding the board , a separate plug for smoke unit and another plug for the fan.

Greg has a pic of one ( on his web site Greg ) that he has a QSI Titan Decoder hooked up to it ( looks the same with out the white piece )

Here is the unit.

Greg it looks to be the same unit.

Can you tell me what could cause the fan from working ?

Are they robust units ?

Thanks

The smoke unit is a standard USA Trainsmotorized unit that is found in most diesels and later hudsons.

Control board looks much the same also.

Well, the fan is about 5v, try unplugging it and applying 5v to it directly… that will tell you if it is the fan itself or the regulator.

I have tons of those regulator boards… that is the standard “new type” smoke unit used in the Diesels.

Thanks Greg

Dan and I spent a little time on this smoke problem …with what unit and boards he had we got a unit working great !

Can you tell us what the issue was?

If you need a spare board let me know.

Greg

First … my fan was toast … and … my board worked almost… not enough power for some reason… two boards , heaters, later we had the right mixture , board/heater, fan combo…

Dan had some from repairs he has done… all good now !

Good deal… I think they can also be damaged if you put the heater power to the fan… I forget the exact voltages in the regulator board.

So, my experience with the USAT regulator board is that it does not run the smoke unit very hard, but I would suspect almost perfect for the caboose.

Greg

I think your right …the board must be diff for the cabeeses…
