I am puzzled.  When putting a disassembled Spectrum USRA Light Mountain back together, I noticed there was continuity between the drivers.  That's a no-go I thought.  But the continuity remained when I checked the loco and made sure the pickups etc. were ok on the tender.  This loco has no decoder at the moment.Well, that can't be, so I checked my Spectrum Heavy Mountain that I had put a decoder in, and which runs just fine.  There's the continuity between the drivers!  Moreover, there is continuity between the wipers on the tender.  And the drivers have continuity with both sides of the tender wheels.But as long as I keep the tender wheels getting power from their correct side of the track, the loco runs.  All functions normal, all CVs reading and writing. (Although the light doesn't work.  I think it is just a burned out bulb and I will replace it with an LED next.)How can this thing run with the left drivers in continuity with the left tender rear AND the right tender front?  And vice versa for the right drivers. And with each other even when disconnected from the tender.?Does anyone have a Spectrum steamer that is wired this way?I just checked my Spectrum 2-10-2s (same decoder installed into [I think]the same Bachmann boards) and there is no continuity between their drivers.
