OK, terribly confused here. Legacy CAB-2 control, Legacy Powermaster, Lionel Powerhouse. One train, one track, couldn't be simpler. Everything worked fine last time I used it a month ago.
Powered everything up today, no movement or sign of life from the train. All status lights on Powermaster and Legacy OK. Checked voltage at Lockon, nothing. No power at Powermaster terminals either. All wires connected as before. No changes whatever to anything.
What could be wrong?
