Hi my name is Katrina. I have a 99 mercury cougar. It's a v6 5-speed car. It has never really given me a problem. It has 146 thousand miles on it and does not leak or smoke anything. I'm new to the site I don't know if anyone can help me. My car started with the problem of the lights flickering and in literally a few months of that the alternator which was custom built by my dad was changed to a brand new one and I even changed the belt as my dad told me its best to change to a new belt with new parts. The battery light started flickering a few weeks later. On a whim just stopped at auto zone and everything checked out as running ok and holding a charge fine. It stayed like that for a week after it started. Today the battery light started to stay on while driving. I had everything checked again and everything checked out ok again. I stopped the car to run in for groceries for dinner and when I came out to start the car it was dead. Would turn over but then started clicking as if the alternator were dead. I was close to home so I walked home and later had my boyfriend take me to jump the car thinking it would charge enough to get me a few blocks to home. Well when we arrived the car started right up without jumping it and I got home. But in the driveway seemed to just slowly deteriorate and die. I tried to start it after that and it wouldn't even do a thing. It wouldn't click, turn over, no lights came on, the door didn't ding when opened. It was lifeless. I did notice the radio shutting on and off today which to me was a sign in the past of an alternator dying. But I just got a brand new one.... I was told by a ford me habit that the voltage regulator in these cars often went bad.... I've never dealt with one before. Any ideas on my car? Or the problem??? Any advice would be appreciated. I tried to tinker with her some but my brother has the book on her as he helped me work on her last.
