I checked again today (after a quick spin yesterday) and the battery was at 12.12v

I disconnected the battery and checked the current drain (as specified in http://www.omegaowners.com/forum/index.php?topic=90619.0) and I'm not sure I'm doing it right.

With the meter set to 20u I get 0.01 on the screen. It's that right? 20u?

Ok those settings were clearly not right. I'm doing this now:

And these are the numbers I'm getting:

That's 0.69 and 1.15 and it seems to start around 0.7 but jump up to over 1.1. Just doesn't settle.

Any ideas?

The voltage has dropped over night from 12.42v to 12.11v

The meter positive lead is plugged into the 2 Amp socket, so you need to switch the selector to its 2 Amp range. If you want to use the range you are presently switched to, plug it into the next socket to the right of the 2 Amp socket.
It has been said on here before but worth repeating - NEVER attempt to measure voltage (i.e. leads across the battery) with the leads still plugged into the current-measuring terminals....your meter will rapidly resemble a failed power sender!

What are you measuring here? wheres the probes?, to measure current, you've diss'ed the battery + lead and are measuring between battery + term and the + lead?

If your doing above and its an Elite, you need to wait for the Rear Ciggy Lighter timer to switch off and if NCDC HU Steering Control lights to go aswell.

Also you probe is in the end one (cant see what it is, probes in the way) but looking at the dail looks like end one is 10Amp, so switch to 10 or if under 2Amp switch to 2 and use the 2A Probe input.

Well this is all complicated... 

I pulled the negative cable off the battery and tested between that and the battery terminal. I waited for... ages...  but it didn't get any better

I'm using the cables in COM and 10A (didn't get a reading using the 2A).

So should I switch to 10 (bottom of the green, on the left) and use the 10A hole? How long do I wait to be sure everything is off? 10 mins? It is an Elite.

Thanks guys!.

Cant remember, think the rear Ciggy switches off about 20mins or so, the Steering wheel lights ? a long time.

Just leave it the DVM inline and monitor whats going on, are you getting any readings when you first start.

Just make sure all doors are shut, HU off etc, might be worth unplugging the Bonnet Switch but I cant remember if that does anything in standby mode.

Check it with the car open and then again locked up and alarm set etc.

Also if its an Saloon, check the rear boot switch (Boot Light) but you've probably been told that already.

What your looking for is current thats going to slowly flatten the Battery,
