If indicator light is still illuminated or blinks, check fan belt tension, "S" and "B" terminals for proper contact and generator output. See GENERATOR OUTPUT SPECIFICATIONS  table.
  3. Check voltage at battery terminals. If voltage is 12.5-15.5 volts, go to next step. If voltage is greater than 15.5 volts, replace regulator assembly. If voltage is less than 12.5 volts, check IC voltage regulator. See IC VOLTAGE REGULATOR  under BENCH TESTING. If regulator is okay, replace generator assembly.
