I replaced the battery in my car. Car ran fine. Then the replaced the terminal because they were lose wouldn't tighen up. So then the car wouldn't kick over. Sat over night then it started drove it 3 miles. Shut it off then wouldn't kick over again.

For some reason, the terminal replacement could have caused too much resistance in the cable, causing no start.

The best way to fix a cable problem is a new cable. Try this first to eliminate that variable.

Naturally I do not know the original reason the battery was replaced, because you may have a starting system issue present as well. The battery may only be one of the symptoms of a large problem.
