Cullen:

My stereo will drain my battery in just a few days if I leave
the face plate on it.  The manual says it draws something like
2.4 amps--and I thought that would only be at high volume.

I measured the draw without the face plate--negilible.  But
with the face plate on but the unit turned off, it was somewhere
near 2 amps!  All I can figure is that the display circuit is
running hard to display nothing!  (Panasonic)

Check the draw of your stereo.  You probably have some other
load on your battery to drain it overnight, however.
