Battery keeps going flat???
 

Hi all,

confused....my 1987 325i starts when it wants to...
Have new battery(3months old)....had the alternator tested.....
they are both fine.
Problem I'm having is......if I don't use my car for 24 hrs...or if I only travel arond 30ks for the day......It won't start without the use of jump leads....
Does anone have any solutions. thank you .:conf

My old e30 did that too, turned out to be a bad hazard light switch, it allowed the board computer to stay on and drain the battery
