Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery. You may also have a battery drain (something that is staying on and killing the battery)

This happened to me on a road trip in my 84 Cougar. It was a long time ago, but first make sure your belts are tight! But I believe you may need to replace the alternator. If the battery is old, its cheap insurance to do both.

What causes the battery to go dead in a 1993 Mercury Cougar when it is parked the alternator seems to be working fine could it be a relay?
An alternator can charge normally but can still drain a battery if the diode(s) are defective. Try this: remove the(red) positive cable from the back of the alternator and then touch it to the post that you removed it from. Remember, this is hot so don't touch it to anything else. If it sparks this indicates the alternator is pulling current, and is bad.
