I started an ERR upgrade to my Polar Express Trainsounds Tender quite aways back.

We determined that the ERR Sound Converter would not work in this application, so I am trying to get back to original configuration.

The Christmas tree is up and ready to setup the Polar Express around the tree and the tender sound is messed up. If I hook the sound board red to positive and track voltage (pickup) and black to neutral then the whistle blows repeatedly. If I swap those around then I get bell continuous. If I push the bell button on the transformer then I get whistle. Is my Lionel Sound board toast? Any suggestions on what to check to confirm?
