Did you get the list of questions I sent you yesterday? I'm holding fire on
making suggestions until I get some of the answers back.

That is correct. The problem exists both with the engine running and
not running. Any other load in the electrical system has no impact on
the problem--it is specific to the intercom and the circuit that
controls the avionics backlighting.
