Parasitic drain test

Paul-C · Nov 28th, 2019, 18:33

I posted earlier (flat battery issue) and I am now back home to start investigating.
Car is charging at 14.9V when idling.
Battery voltage one hour after stopping the car is settled at 12.4V
Can I check with you the correct procedure for a battery drain test as I don't want to follow a youtube procedure if it's wrong for my car (17yr manufacture XC60 D5 auto )
Do I need to lock the car?
Battery - ive cable disconnected and multimeter (reading amps) between battery negative post and cable.
How long do I wait to allow the car to go to sleep?
If I progress to checking parasitic drain tests across fuses how do I check the passenger and boot fuse boxes if the car needs to be locked? ie, door opened
Thanks

Given how difficult the various fuse boxes are to get at to pull fuses it will not be easy.
