Both fixed and variable channel 1 affected. Power through unit, and out to the tracks, but remote doesn't see DCS engines on the tracks.
Fixed and variable 2 work fine.
I've tried exchanging wires to other loops of track, and any track powered by channel 1, fixed and variable has same problem.
Differen engines, too. Doesn't find any of them, so I isolated issue to the channels, any ideas?
