alternator????whats wrong?
well i changed my alternator a month ago and just changed my battery last week and my car was charging up fine i could see at the voltage meter that it was charging. but now it is not and my car just runs on the battery. i did the alternator test where you take off one of the post and the car should stay on if the alternator is fine, then immidiatly i get a response that the alternator is kicking agiain so i put back the battery post. and it charges fine after that till my destination. what could be the problem?

Put a multi meter on the posts, you should see around 12.5V with the car off, and around 13.5 to 14 with the car running.
You could have bad battery cables. They werent that great when they were new, and now they are around 20 years old.
