battery drain on a 159 Sportwagon 2009
Battery is draining in a day and unable to start so checked the draw yesterday and its pulling 3.5A which is way too much.
Pulled all the fuses and relays but no changes, even the PITA board by the rear light. 2 things made the amps drop and that was removing the 70A midi fuse (cant find what circuit this protects in the manual) on the +ive battery post and pulling the plug on the bottom right side if the internal fuse box which has a large red and black cable going to it so I guess its powering something fairly major. No mention of this is the owners manual either, very helpful.
Any ideas what this could be? Sorry didn't take a picture.
It on trickle charge now so at least its being topped up but need to get this sorted. I've changed the midi fuse on the battery post but this didn't cure the problem.
