My ZW-L is about 4 yrs old. I have power going into the unit, but no power coming out of any of the A through D posts. The volt/amp meters are all backlit but there's no voltage or amperes shown on them. I've reset all of the circuit breakers still nothing. I was running trains and instantly lost power to the rails, no indication of any shorts anywhere in my layout. Any ideas or suggestions would be appreciated.
Thank you Dana
