Car has been checked again, battery flat and showing 1.8 to 2.3 amp draw on the battery when everything turned off, checked akk fuses etc all ok, checked alternator and radio, boot light all ok, so AA man has gone, battery is fully charged and I will remove earth connection which should stop the leak in the meantime. earliest I can got my garage to have her in is next Monday, any ideas, could it be the security system?
