Alternator in my truck was FUBAR. I went to FLAPS and bought a new one. Both batteries passed load test. New alternator shows 12.94V at the batteries. This seems low to me. I took it back to FLAPS, they put it on machine and said it passed. My Idiot light remains on. Peter, The light should intially come on when you turn the key to run, indicating a current flow towards the alternator, which is used to exite the winding and get the altenator charging. As soon as the alternator is putting out current, the feed back voltage to the light should turn it out In your case, if the light remains on with the engine running, I would suspect the wire to the alternator is grounded somewhere between the alternator and the key switch. This would mean the alternator is NOT getting excited and output, on your vehicle would be zilch. On the test bench, the alternator would look OK.
