I have an older trainmaster 90 watt transformer by Lionel. I would like to hook it up and see if it works. However looking at the connection points I am lost. Where do I put the track wires? I am not familiar with this type of connection. The connection points say A B C with U underneath. I will post a pic as well. Thanks for your help! I have 2 other transformers that doesn't work any more. I think the family fried it in December :tb-sad:. They are a CW-80 and a multi control type 1033. The CW-80 gets power for the little fan turns on but nothing to the track. The other just doesn't put out any more.
