Thanks

ANSWER: Greg, sounds like the small red field wire is broken inside the wiring harness.  I would run a new one from the connection block on the firewall down to the alternator and see if that solves the problem.  Sounds like a big draw on the system.  Let me know what you find out.  Roger

QUESTION: I ran a new red field wire from alternator to connection inside firewall. I still
get the alternator light on even when key is out of car. The alternator light
only goes off when I turn key to on ( oppisite what it should do) or when I
take negetive lead off battery. Your wright about the draw on the system I
have looked over all wires and can not find a short. I also was using
alternators from auto zone and switched to a Bosh but still get the same
results. Help !!!!! Your advise is helpful.
Thanks greg  write or phone#  

Answer
Greg, Interesting.  Pull the instrument cluster and see if anything is loose.  If all looks good the next test is to find the circuit.  It may be fuse 8 which controls the central locking and other stuff.  Do you know how to perform the draw test to see which circuit is bad?  Roger
