SOURCE: alternator light on
The alternator is not producing any power . If it were the engine would run without the battery. Check the wiring on the alternator. It must ave an exciter wire to make it work.

Hi, I can't tell you exactly what is wrong because there is too much involved at this point, what with 2 shops working with it, but I can give you some advise on what else to check. On the alternators and the wiring that supports them a small volt charge is taken off one of the slip rings, where the brushes ride, for the purpose of turning out the light. As I remember, this is a yellow wire that runs back to the dash.
To the alternator, it would be one of the wires that plug into the side of the alternator case.

If you replaced the alternator and you have checked all fushes and wires. you most likly recieved bad alt. I would take it off and have it tested.
