I'm using a Digitrax DCS100 Command Station Booster with an attached NCE PB-110A Booster. Over the weekend, I de-railed an engine causing a shutdown of the system. After removing the short, I could not power up the system. If I remove the PB-110A booster and power the track from the DCS100, I have track power, but when I reconnect the PB-110A, I loose power. Did I fry the Booster or is there a switch in the DSC100 that needs to be reset?
