Discussion
I've noticed that with everything 'off' in the car including the interior light - but with a door open my Accumate trickle charger fails to maintain the 'high' battery voltage. Presumably the door or main ECU is drawing current for a 'door open' warning as there are obviously no relays for the door switches to activate the interior lights. Just seems a slightly odd logic and could lead to a flat battery if you didn't realise there is an additional current drain over and above the normal level. Comments?
Bob,
You could be right in assuming the "door open alarm" draws something more than 100-200 Ma. I guess the warning buzzer would account for some of that.
Best way is to check parasitic current drain - YouTube video here:

So - with door open and multimeter set to MAX current (initially) and connected as advised in video, I'd pull fuse to lcd display (??) and see if that answers your Q.
