The alternator light will not go out on the dash. There is no voltage increase at the battery at idle and at 1500rpm. I have changed the voltage regulator followed by a remanufactured alternator; all the connections have been cleaned and the wiring was reconnected as spec'd. What else can be wrong?

Inspect wiring

Disconnect the voltage regulator connector and jumper A to F terminals-what you doing here is full fielding the alternator if the voltage increase the regulator is defective if not the alternator. Let me know
