Reply to "Lionel S-4 Smoke Regulator Issue"

The smoke regulator is to allow three levels of command selectable smoke volume.  As the previous post suggests, the smoke unit should have any 6 ohm resistor replaced with the 8 ohm resistor.  As for the exact part number, it really helps if you provide the exact Lionel product number.

GRJ,

Model # 6-28548. The regulator is available from Lionel. The resistor is 8 ohm from the factory. I was just thinking of a way to bypass the reg but it makes sense Lionel used it to stage smoke volume hence the brown serial data wire. I'll just order a replacement.

Thanks again,

Dan
