measuring the quiescent current.

I agree, some electronics wake up, even with just a slight change in
voltage across them.

3.6 amps would run the battery flat in less than one day.

A normal figure would be more like 0.03 amps (30mA)

My car, loaded with electronics, sleeps at 20mA, with an odd higher
short pulse, which I assume is for the alarm system.

That's good. I've got quite a bit of extra junk on the old Rover, much of
it home designed/installed. And couldn't get it down under 30mA. The
original central locking took about 10mA. Got that down to under 1mA.
