Am i better off goin to a junk yard to buy an alternator for my car??
A bad alternator wouldn’t keep your car from starting. If it begins to turn over, but the battery doesn’t have enough juice to start it then it would be your alternator. From what you’re saying, it sounds like your starter is going out. It probably has a dead spot in the armature and when it lands on that spot, it won’t start. Take it to your local auto parts store and they can test the alternator. If it’s good, then it’s most likely your starter.
