My layout is wired for Legacy with 2 power blocks. Each block is powered with a separate PH-180 feeding a TPC 400 which is connected to a PSX=AC circuit breaker and then to the track. Both blocks share a common ground or return. Both command and conventional engines run fine within the blocks, but short out when crossing the middle rail gap between blocks. Both PH-180s are in phase as they have polarized plugs. I have checked and re-checked my wiring, and don't see where I have crossed power and ground connections. The PSX breakers are set to trip at 8 amps. Both TPCs are set for full voltage.
I believe I read somewhere that a common ground is OK with multiple TPCs. The PSXs try to reset after the short, but then re-short again. Could these be the problem? Any advice is appreciated, as usual.
