Doesn't that make your airplane "illegal" (technically speaking of
course).

I thought the total draw of an electrical system could not exceed 80%
of the output capacity of the alternator.

Am I incorrect, or is there more to this concept?

The operative phrase is "at idle". At cruise rpm the alternator would carry
the load quite well.
