I have the Lego City 3677 Train with remote control.
I've just changed the batteries in the power pack for the first time on the train and I can't get it to work. The green light isn't coming on. I also put batteries from the same pack in the remote control unit and the light comes on in that. I've checked the frequency settings and they both units are set on 1.
The batteries are Varta Longlife Extra alkaline made in Germany.
On the back of the instructions is the train trouble shooting web site but it doesn't seem to work www.lego.com/trains.
Are there any known problems with these units/sets? Any suggestioins on what to do?
