Done a quick search, couldn't find anything useful.

Issue is sometimes when the car is sitting over night the battery will be flat in morning.

Things I have done...

Boot light doesn't go (figure can't be that as I can't get it to go normally).
Alt is charging fine, multimeter proves this.
Battery is new.
All interior lights are off.

Any ideas?

some batteries will say they have the correct volts with the meter but once you hit the key are almost dead flat instantly, ive had this happen, need to find out the date on the battery because anything over a couple years old it will probably be stuffed, altho some batteries have lasted up to 8 years in my dads cars :shock:

Main reason is it will start all day long even just with a jump. Can start it like 10 times without issue, it's only now and then (5 times this year) that it will be flat in the morning only. The smallest jump it will start so I don't think it's the starter?

These 2 things sound like my issue, being intermittent I'm reluctant to take to a auto sparky...

Hey there,

Do you know how to check for current draw using the multimeter. If not there will be three sockets on the front of the multimeter. You will need to plug the red lead into the plug that says 10amp fused, then switch the multimeter to 10amp DCvoltage (the symbol has a straight line up top and 3 dots under the line), disconnect the negative terminal off the battery and put 1 lead onto the battery and 1 onto the lead you removed from the battery.
The multimeter will give a reading and if its gererally above 200ma or 0.20 then you have a current draw problem. ( make sure all lights and doors are closed and ign off when doing this test. ) So after finding you have too much current draw start pulling fuses until the current draw drops on the meter and you have found the circuit that is causing the current draw. From there start asking questions as to what could be draining the battery.

Hope that helps.

Cheers Joel

Don't know if it's related to your problem, but I accidentally left my EF in Drive when I got home. The battery was dead flat next morning - only enough juice to unlock the doors from the remote once, then nothing. Never happened before or since, but I have never left it in gear before or since either. FWIW.

Have pulled the 'courtesy' fuse (no lights on I can find though) drops to around 0.40. Will see how we go from there.
