If it has a switch, it might be set to 2r?

That results in no power or anything. Per GGG and my own experience last night in troubleshooting a similar PS2 3V engine with 2R/3R, the polarity switch is the 2 wires from the trucks for the left and right side wheels, the 2R/3R switch is then after that and connects either the 3rd rail pickup and/or outside wheels to the 7 pin input harness of the PS2 stack. Point being- it completely disconnects the 3rd rail pickup when in 2 rail so again, switched the engine would have no power- nothing at all on a 3R track.

This does run in conventional just not DCS

This particular locomotive had been running without a problem since I bought it last summer. Never an issue with it until now. It does run conventional as it should but trying to run command is off the map.

And, I agree, sending to a tech is the best bet for fixing without invoking more damage.
