Did you mean "four" drops of fluid?
Four drops is not nearly enough fluid....15 would be better.
The smoke unit produces smoke, but the fan, which generates the synchronized puffs, doesn't spin. You can see smoke lazily oozing out, but there are no puffs. This is confirmed when I take off the shell. I removed the top of the smoke unit and checked to make sure the fan could turn freely.
When this first happened at the beginning of April, I put in an entirely new smoke unit, but that did not solve the problem. So I dissembled both smoke units and tested the motors and the continuity of the wires and the tracings on the smoke units' simple PCBs. Both smoke units appeared to be fine. To the best of my knowledge, the smoke unit fans weren't getting a signal from the locomotive's main board.
Having it sit at Charles Ro for a couple of months did solve the problem, at least temporarily.
The locomotive's manual specifies adding four drops of smoke fluid. I use the eye dropper included with the jar of JT's Mega Steam (coal-fired scent).
