Integral Regulator

Connect a voltmeter between main terminals of battery. Install a 0-60 amp ammeter in series with alternator main output cable, at its connection with starter solenoid. Start engine and run alternator at 5000 RPM until ammeter shows an output not exceeding 7.5 amps. Voltage reading should be 14.1-14.5 volts. If reading obtained is unstable or outside specified limits, the voltage regulator is faulty and must be replaced.
