The battery is not charging, probably because the alternator has no output. Exchange alternators are readily available but not cheap. Check alternator belt tension. Remove, inspect and replace alternator carbon brush pack as necessary. After that, if still not charging, swop out the regulator.
This indicates a charging system problem - 90% of the time it's a bad alternator.

Check your maintenance manual. It's in there.
