There could be several causes for the battery charging circuit warning light remaining "ON," and some that come to mind at the moment include: * The battery is seriously undercharged. * The alternator or generator is not working. * There is a defect in the light circuit.

The light next to the battery warning light is the fuel injection system warning light. If it comes on and goes off after a short while it should be ok but if it stays on for longer than 5-10 minutes then get it checked out.
There are several warning light on the instrument panel. There is a high water temperature light. There is a low battery charge light. There is a low oil warning light.
