new battery but won't start
My well loved 98 Z3, 185k miles, wouldn't start after 5 days of sitting. I put a new battery in and then it wouldn't start again after 5 days of sitting. It lives in the city and has never had a problem there. It's starting problem is out on an island....more wind? colder? Would any of that matter? Took it to the well respected bimmer shop, they had it on a machine to test the drainage problem...I called it a heart monitor... overnight and found nothing. It's a good shop but he said sorry, I have no idea. And car started next day but the day after, you guessed it, no start. I'm taking to another well respected shop today, but wanted some ideas of what might be happening to my sweet sweet car.
