With the Z4000 out of the loop everything is working. I have wired non-derail for for two of the three switch motors and all is working well. I will wire the one remaining switch motor tonight.
To do list:
1. Re-trace ground circuit and make sure it is ok
2. Wire reaming non-derail
3. wire switch motors for the two crossover turnouts
4. wire dwarf signals for the crossovers
5. wire the four de-couplers (two Gargraves and two Atlas O)
