bus wire | O Gauge Railroading On Line Forum

Hello everyone, i have a strange problem with my bus wire. when it is hooked up to my MRC Dual accessories post the 022 switches get power 13.4 volts. I needed more power so I switch the bus line over to my ZW accessories post and I get nothing. The ZW is putting out 19.4 volts across all terminals. My old ZW went bad but it powered the switches fine.

I have no idea what's going on?? Any ideas??

Thank You

Because the MRC Post is a 14VAC line:

I'm not sure what you mean your ZW gets nothing to the switches... It sounds like a layout wiring problem of some sort (ie not using common ground, not properly phasing power sources or whatnot)
