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,
