The alternator may be putting out some amps, but the regulator inside is failed. The alternator is the first thing to replace when the battery lamp comes on in these vehicles. Also make sure the battery is not leaking acid. Remove the positive and negative cables from the battery and look for corrosion. If corrision is found, you'll need to replace the battery and also take the battery cable covers off to clean the contact pads down to bare metal. Make sure all corrosion is removed. Russtech67
