Lionel Hudson smoke unit issue

The smoke triac may have failed.  Is the wiring to the switch back to smoke intact?

Always worth trying a Reset.  G

After the reset, try swapping in a new R2LC-C08 and then reprogramming that one.

Did you measure the resistance of the smoke resistor?  It should be in the 27-30 ohm range.

Thanks to GGG and gunrunnerjohn for your reply. I am not sure what and where the smoke traic is. There is no smoke unit switch on this version. I installed another R2LC-C08 board from another Hudson, I ran a reset with the replacement board and with the original board and nothing changed. I checked the resistance at the smoke resistor and and got a "0" reading so at this point it seems that the resister is bad. Does anyone know where to get a replacement? I am still baffled by the low input voltage. Also the only wick in this unit is thin and fits over the resistor. Can additional wadding be installed to soak up more of the fluid? Thanks

YIKES!  If you got a zero reading, it's shorted!  Probably the hot lead of the smoke resistor is grounded.  I suspect the second R2LC now has a bad triac as well.

If the resistor was bad, the normal failure mode is infinity, ie. an open circuit.

Here's where the triacs are on the R2LC.  These are fairly easy to replace if you can solder on a PCB without killing it.

I have the same issue. I finally ran the Century 773 after 15 years in the case. It was smoking good for two weeks. I sure I flooded the unit, got fluid all over the boards and stopped smoking. But all other sounds are working. I been trying to dry it out. Did you find a solution? Was it the resister element?

Yes. The resistor was bad, I replaced it, packed some insulation around it and it now smokes good. I bought the parts from gunrunnerjohn so you may want to write him for the parts. 

Thanks, I'll do that.
