Hi all, I have long visited here for information, but this is my first real posting. I have a lionel 6-34776 SD40-2 NW 6121 that I'm having trouble with. I recently managed to get it apart. The hidden bell that kept it attached never showed up in any tear down video I watched! Now that I have the engine apart, I pulled the smoke unit and began tearing it apart. To my surprise, after I thought I flooded the unit, the batting is almost bone dry. So this is the first problem is it still ok to go with 20 drops when applied right to the batting? Next in looking at the PCB for the smoke unit I see that the motor is marked with a positive marker and attached is a red wire. The other wire from the motor is black. That makes sense to me however when looking at the PCB I see it is marked with a + and - where the motor wires are soldered on, but they soldered the red wire to the - location and the black wire to the + location. If my motor is running backwards and sucking air in, that explains my lousy smoke. Or is this some industry secret and its supposed to be "backwards"?
Any thoughts or experience you can lend me I will greatly appreciate. If I do need to rearrange the wires it is no problem, I'm very comfortable with my iron, I just don't want to change it if its supposed to be that way.
A little difficult to see but the wires are backwards from what I would have expected to see...
