I recently started getting a trouble error on Output 2.  It was working well for weeks, then all of a sudden trouble.  It is followed by the pleasant smell of lightly toasted wires.  The only thing hooked into Output 2 is a siren that was part of my old system.  If I remove the wires completely I still get the Output 2 trouble.  Any ideas?
