Thanks Rich for the link, and others as well. That might be the ticket.
PLCProf: I have mostly incandescent bulbs ~ 4-5 buildings have LED's. The thought of changing them all to LED's is overwhelming as its taken me years to build some of the custom buildings ~ and I used the bulbs they came with.
I did some quick math and at 4-5 amps x 10 volts per each throttle of my Z-4000 that's only about 100 watts (VI = Watts) total. Yet, isn't the Z-4000 rated at 360 to 380 watts? I am not sure why its having so much trouble (pulsing) at what I am using it for? I'll confirm the amps later, but am pretty sure the above is correct. Could it be the thin building wires ~ guessing their 22 gauge can't handle the load being pushed out? I have about 25 buildings on the one transformer at this point ~ about 10 of them are 6 stories or greater.
