@Jon G posted:We saw this occasionally at MTH. Repeated connecting/disconnecting of the drawbar enlarges connections inside the 6-pin harness. Swapping end for end sometimes fixes it because the harness connection in the board doesn’t move. I used to disassemble the harness wire by wire and tighten the “clamp” that grips the pins on the drawbar.
This makes sense. The engine in the video above worked perfectly until the customer had another train crash into the back of the consist in tow behind this steamer which is when this issue started.
Another question for you Jon. MTH used to include a square plastic bushing that went on the tender post of the wireless drawbar, I've only seen this part on the earlier PS3 steamer but it seams to have disappeared around 2016 or 2017. It seemed to help keep the load of the consist off of the the electrical connector and on that metal post.
