The first thing I would do with this vehicle is do a check of the charging system output when the vehicle is running. First, check the battery and ensure it is fully charged and able to handle a load. Then, monitor amperage and voltage output of the alternator at 2,000 RPM of engine speed. If it is over 13.8 volts (hopefully over 14) and over 60 amps (specification is 71), then the charging is working as it should be, and the battery light is caused by something else. If the readings are lower than those specifications, then I would focus on the charging system as an area of opportunity before attacking any other problem.
