So I started to wire-up my switch machines this morning.  Wired them exactly as per the instructions.  Just to preface, I am using a Z4000, MTH Terminal Block, TIU/AIU set-up, Ross switches with the DZ-1000, and 22g wire.

The AUI appears to be working properly, I can hear it clicking when I use the remote to operate the switch, but the LED's are not illuminated on the DZ-1000 and it is not switching.  I started out on the 14v output of the Z4000, then moved to the 18v (right side) of the Z4000 and moved the arm to 18v.  I tested the terminal block to ensure it is getting power and it is, any ideas of what might be wrong?  Please bare with me, this is my first time using/wiring these switch machines.

Thank you,

Darren Caruso
