Battery drain 147
Any help would be appreciated guys.
Ok, if I leave my car locked with the battery connected, after about 9 + the battery drains, It won't turn over at all and just dies on me. Jump starting from another car works and the car starts immediately. the battery has been drop tested by my mechanic and the alternator checked, both the battery and the alternator are fine.
If I disconnect the battery when I park up and reconnect it in the morning, the car starts fine, so the battery does hold it's charge overnight, although when reconnecting it back in darkness. there isn't a really big spark as such.
I have a multimeter but I've not had the time to look at the car and see of I can figure out whats causing the drain. is there any common faults on the later 147's that drain the battery mine is a 2008 57 plate.
I've had no warnings when driving, no airbag lights etc, nothing untoward. I've also been around the car in total darkness looking for any light thats has been left on, including the rear clusters as I've read thats sometimes a problem and they have been off . the boot light also off as I switched it off manually.
How do I find the problem?
