GregM posted:Is there an axle wiper (copper colored strip with single hole) on the other tender truck? If yes and it has a solid black wire attached to it then that unattached wire is most likely supposed to be attached to the front truck's axle wiper. You would need to confirm that the other end of the loose wire connects to the wire on the rear truck before soldering to the front truck axle.
On any other given day I would not have understood a single word of that mumbo-jumbo but I can confirm that the solid black wire is connected to that axle wiper on both the front and the rear truck. This wire however appears to be for something different, and it is NOT the contact roller (there is a black/white colored wire connected to the front pickup roller). There appears to be a small soldered blob with the tiniest hints of copper-colored something on the drawbar of the tender. This is the first steamer I've gotten that has sounds, so I don't know if this part is significant or not but since it caught my attention I'd like to know if this is what it was connected to, or if it served another purpose.
