Check the big red wire on the back of the alternator for power. The wire likes to get corroded in half inside the casing but is still held together BY the casing. you can even take a jumper cable from the positive side of the battery to the big/single wire on the back of the alternator. Now , you could have a bad ground also. take a voltmeter or test light and with the ground of the tester on the ground of the battery check for power on the case of the alternator. Another thing , does the alternator or charge light on the dash light up woth the key off? the alternator knows to "start-up" or "field-up" by the power it recieves through the bulb before the engine is started. once the engine starts the small brown wire on the alternator goes hot and shuts the light on the dash off cause it now has power on both legs of it. if the bulb blows then the alternator won't field-up. good luck.

SOURCE: airbag light stay on 2003 chevy tahoe

The air bag light will remain illuminated if a fault has been detected in the air bag system.
The onboard computer will need to be interfaced with diagnostic equipment to read the fault.
This is also the only way to reset the light.
Good luck, I hope this helped.

Either the alternator is not charging the battery or you have a draw that is draining the battery. The alternator must have power to the field coil and a good connection from the charge terminal to the battery in order to charge. You can confirm the batrery is charging by checking the voltage at the battery with the engine running. Voltage should be at least 13.5vdc. If yes, see dead battery section at link below.
