One of my other repairs I’ve been attending to for a friend was to replace a Seuthe type smoke unit in a Weaver Pacific with TMCC.
Normally he would’ve preferred a fan smoke and synchronized puffs, but his budget is tight and the engine has a rubber band style shaft drive for the can motor, not a flywheel.
Anyways, I bought a replacement one just the right size for this particular locomotive, but when I rewired it and connected it to the circuit board (pair of wires that are black and white), the smoke unit didn’t do a thing.
I can’t tell if I should just bypass the circuit board and just wire it to track power or not, since I don’t know what the voltage was on the old unit. This new one runs on 16-22V
