Yep, now its drawing 10-20 mA.  With the new switch leg, the main power only
is switched, the memory power is constant at 10-20 mA.  The surprising thing
to me is, that even with the unit Off, even with the faceplate removed (no
function whatsoever) that it draws 0.68A.  With nothing going on, you would
think it would not draw anything except the 10-20 mA.  That was my
assumption until I found out otherwise :-)
