Smoke Unit Wiring On A Lionel 2025

[servoguy]

I think you should trace the wiring.  The smoker may be grounded where it is attached to the frame.  The 2nd wire may go to the headlight.

Traditional smoke generators are connected to the track voltage.  This usually involves a connection to the locomotive frame, which is connected to the outside rails, and one to the terminal on the e-unit that is itself connected to the pickup.

Try this link at Olsen's trains.  The manual has a complete wiring diagram that should tell you what you need to know to reconnect the smoke unit:

Alcohol will normally clean up an e-unit, but tuner cleaner is better still.

Hello All:

  My grandson noted to me yesterday how my engine was not puffing.  I took it apart and found the 2 wires from the smoke unit broken off of their connection, which I think is on the E unit.  The smoke unit appears to be a new liquid unit and not the old pill one.  Do both wires get soldered to the E unit?  If possible, explain the wire placement of such.  Also, are parts available to rebuild these E units, cycling of such was inconsistent, or would just a clean up with alcohol sufice?
