    Sounds like someone doubled up spare wires. Are there two wires per terminal?

    The transformer has two terminals, one goes directly to the chime, the other goes to one terminal at the pushbutton, and the other terminal on the pushbutton goes back to the chime.

    Should be as simple as that.
