In further research, I got out my owners manual. There is a section on fuses that clearly states. "IF THE VEHICLE IS PARKED AND NOT OPERATED FOR PROLONGED PERIODS. PULL THE "ROOM" FUSE.
Not the best design !
Most auto manufacturers shoot for about a 2 week window before running a battery flat from those types of loads.
BTW Tinstar you get a GOLD STAR for using the proper procedure with the multimeter ! When measuring an unknown amount of Amps, always start with the HIGHEST amperage scale, which usually has a separate input.
There are some reasonably priced (<$50) "amp clamp" meters on Amazon. I bought a Uni-T B4Q094 last year.
For individually fused circuits, if you can find a chart of fuse resistance on the internet and know how to use Ohm's Law, you can measure the individual circuit draw by just measuring the voltage drop across the top of the fuse (yes, there are spots to do this on top of all automotive type fuses). No adapters reqired. Nothing to unplug.
