Reply to "Minor wiring change, now neither TMCC nor Legacy track signals working correctly"

Ah, well, the symptoms always make perfect sense once the diagnosis is figured out.  I overlooked the fact that I hadn't run trains since adding the PSX1-AC's to the system, before adding the new 12 gauge power feed wires (seen entering from the right).  All wired now with jumper on each PSX1-AC so trips at 12.2, not 4.8 amps.  The starting current for the 3 prewar-style or 4 DC can motors in the two diesel lashups in question just touched that 4.8 amps.  The reset is not instantaneous, there is time to turn things off.  After reducing motor current, it took a fair bit of time for the power to resume.  Since the setup is hanging from the ceiling for better radio signal from remotes around the basement to bases (TMCC and DCS), the work is overhead and the neck only does that for a while before needing a break.  Finally all tidy to my satisfaction.  Your TMCC DM Buffer is nicely displayed, GRJ.  Thanks for speculating with me while I got another flat spot on my forehead to add to the collection there
