Hi, for some reason my battery has been dying out and didn't charge. It has happened a couple times. I changed the ground on the battery because it was breaking it lasted about a month. Then when I went to go somewhere it wouldn't start, but the night before it started with no problem. Not sure what's wrong.

Hi,

First, make sure the battery terminals are clean and tight. If you haven't already, you should try load testing the battery. It's best to do it with a machine, but here is a link that explains how to do it at home:

If the terminals are tight and clean and the battery is good, we need to check the alternator's output to the battery. It isn't hard to do. Here is a link that explains how to do it. You will need a volt meter or multi meter.

Do this and let me know the results so I can guide you.

Take care,
