Jeff, I’m not convinced you’re out of the woods mechanically just yet,....I could be wrong but looking at that video, that one wheel set looks mighty sketchy,....that’s the chances we’re all taking with these engineering samples, is all the sorting out that needs to be done before we wind up with a functioning model.....what I do on a circumstance like this, is either wire in a simple cheap bridge rectifier from the pick up rollers and run it real world on the layout, or just wire it up straight DC and temporarily wire a loop of track and test it with a straight DC transformer....and having a way to monitor amp draws is helpful.....testing in an environment like that is far less expensive than buying boards after boards.....I’d run it somehow on a loop of track somehow, someway shell on, and look for deficiencies that way,....try it with out the shell, and with,.....best to sort out known mechanical issues now, rather than an issue wiping out a board...also, no need to grease dog bone coupler cups,...that’s a nylon dog bone, that grease will just sling everywhere making a mess....
