@GGG posted:Is this PS-3? Regardless, the 2R-3R switch on the tender only connects the tender wheels together and properly routes engine wiring. The engine wheels remain separate. Right side as a source of AC power only in 2R. If you are a 3R only you can go in and move the right side wires and ground them to the chassis so both side provide ground.
PS-3 does not care about polarity. PS-2 does which is why they also have a polarity switch to ensure the rail with Red DC signal get to the red wire of the PS-2 board. G
PS-3 doesn't care about polarity, but if the wires are reversed after the TIU, the DCS signal would be on the outside rails which are not always connected depending how the blocks are set up, especially for non-derailing switch operation, no?
