I have a 20-20175-1 PS 2/3 VO-1000 that appears to be electrically dead along its right side. It operates normally in 3 rail DCS mode only if it is on old style tubular track or Lionel Fastrack with electrically connected running rails. On any track with electrically independent running rails (RealTrax, Atlas O, etc.), it will not pick up power and run unless the of the live side of the engine is in direct contact with the live running rail or the two outer rails are jumped. It also dies on switches.
Electricity is not my thing, but I suspect the problem may be in the DPDT switch use to select 2 or 3 rail operation. Can someone post an illustration or schematic of how it is supposed to be wired or offer some other possible solution?
