    Cool Alfa 159 2.4 jtdm - parasitic drain on battery

    Hi - This is the first time I've ever experienced this - there is a parasitic drain on my cars battery, and I don't know what's causing it. I switched off the radio and done a few checks - is there a come fault that causes this as its not my cars battery, had that checked and changed. When I leave the car over-night, in the morning the battery will be flat if I do not charge it .. any ideas, is it a common fault?
    I would really welcome any insight as to what is causing this.. any help or guidance appreciated

    I think you do have a fault there somewhere, I can leave my 159 for days and she always fires up, unlike my 156 which drains her battery in 3 days. My 33 is the best I can leave that weeks, no drain at all...but then again no alarm or anything!!

    Welcome. Are you sure it's not just the battery on its way out?

    It could be the alternator. Tun the car, put a bolt meter on the battery terminals and you should get a reading of 14.4v.

    If it's below14v it's your alternator.
