Hello and welcome to FixYa!
If the battery light is on, I strongly suggest that you have
the battery charged. It can be an indication of a weak battery or a faulty
alternator. If the battery light still on after charging then the problem will
surely be on the alternator itself. If that's the case the alternator should be
replaced to resolve the problem.
If the battery won't hold charge even on a new alternator
then the problem will be on the battery itself. It surely is in the end of it's
service life and replacement will be necessary.
You may try to reset it to by removing the positive battery
connector, letting it sit for at least 5mins. then reconnect it again. This
will reset the system and can get the battery light off.
Hope this helps and thank you for using FixYa! Have a good one!

So, it runs fine once you get it going? When you leave it overnight, it loses power? If so, drive it, and disconnect the battery and reconnect it in the morning. If it works, you have a power drain somewhere.
