So i had a dead battery yesterday and then jumped it. It started right up but then kind of switched over to this whinning noise that sounded like my altenator so i sat in my car at it was "idling" at like 2 grand and staying there. and i was like okay? i gave a little throttle and the whinning noise would get louder and would rev up to about 3 grand and stop. so i let it sit there for a while and let it do its thing. Well i needed to get home so i unhooked the battery for an ecu reset i tried to start and the fuse box started clicking, so i figured i prolly blew a fuse. I removed the cover and got my friend to turn the key to see if i could see anything, well after about three times of that it started and acted normal? Can anyone tell me what the hell happened?
