Yes, I only set it up once a year; it is connected to DC, and I disconnected and reconnected the wires to the power pack to ensure that the connection was tight. Only thing I did not do was clean it. I'll try that and get back with you. Thanx.

Just set up my HO electric train set, plugged in the power pack, flipped the switch but nothing happens. Don't have the user guide anymore, need help to get it running again.
