Transformer Issues

Are you sure you're connected to the proper terminals?  You should be connected to the two left terminals.

The lead on the right is the base terminal. The one in the middle reads 15-7 volt. The one one the left is straight 15v. The middle 15-7 volt is dead. If I connect to the straight

15 volt terminal the train operates without control.

Sounds like your carbon roller is gone or not making contact with the secondary windings.

 Could also be the control arm(with handle locked down) inside is not properly lined up with the copper carbon roller arm. There would be no downward pressure being forced on the roller arm to make contact with the secondary windings.

   You are going to have to remove the cover to be sure. If you are not confident with electrical, get someone who is to do this.

Thanks Al, I'll take a look.

I think you understand this, but you are connecting to the accessories terminal (the left terminal at 15v).  There is no control of that terminal by the handle.

If you go to page 14 of this document, an AF transformer like yours shows how the left terminal is for accessoroies - and thus you need to have it attached to middle and right terminals.

As albertrains suggest, have a reputable repair shop fix it.  Change out the cord while you have the thing open.  Only a few more $ for added security.

 Of course making sure you connect the BASE post and your 7-15Volt to the track is necessary! lol  Al

I thought the constant voltage was being used, too bad the variable is dead.  You may be better off considering a different transformer, depending on how much it costs to repair that one.
