So in June we purchased a 2007 Accord EX for our daughter. This morning after it sitting for over a week and a half it would not start. Battery is completely dead. So I got out the battery charger and turned it on. After 15 minutes of charging, still dead. No lights on the dash or anything. My husband told me to turn the charger to engine start and after a couple of seconds the horn started blowing like the car alarm had been set off. There was also a buzzing noise coming from either the battery or the fuse box. I honestly couldn’t tell. Shut everything down. Husband said put the charger back on 6A boost charge. Did that and now as soon as the charging indicator light comes on there is clicking noise coming from the fuse box. Any ideas?
