I’ve been working on a thorough clean-up of my Uni I which was very grimy and dirty. I’ve already tore down and cleaned the adjustable bed which was frozen. That went smoothly thanks to the fine documentation from previous posts. Currently, I am dealing with a problem of immediately blowing a fuse when I put the power carriage into forward. At this point I don’t really know how to begin to trouble shoot this problem, and I am looking for direction. The rails and bearers are clean and lubricated. I have not cleaned the cylinder/gears at this point, but they aren’t too dirty. I realize that I may need to provide more information (and please let me know), but I appreciate any direction that can be given at this point. Thank you. Serial No. 23002.
