Connect a voltmeter between positive battery terminal and disconnected negative battery cable. Increase engine speed to 2000-2500 RPM and read voltage. If voltage is not within specifications adjust voltage regulator. If regulator cannot be adjusted to within specifications, replace alternator regulator.
