Alternator Assembly, Exploded View (Sheet 2 of 2)(7) Using an ohmmeter, check continuity of each phase of stator assembly. Replace stator assembly ifohmmeter indicates open circuit of one or more phase.(8) Visually inspect rotor assembly for rub marks and burns or other evidence of shorting. Inspect shaftfor worn key slot and bearing surfaces.(9) Test rotor assembly as follows:(a)(b)(c)(d)(e)(10)(11)(12)(13)Install rotor assembly in test setup shown in figure 3-6.Adjust rheostat until voltmeter indicates 20 Vdc.Ammeter should indicate 2.8 to 3.0 amperes at 70° to 80°F (21.1 ° to 26.7°C).High current reading on ammeter indicates low resistance, or a shorted rotor warning.Using an ohmmeter, check resistance across slip rings. Resistance should be 7.5 to 8.0 ohms at anambient temperature of 70° to 80‘F (21.10 to 26.7°C).Replace rotor assembly if inspection and test requirements are not met.Inspect voltage regulator connector, cover assembly, and voltage adjust for cracks, corrosion, andevidence of shorting or other damage.Inspect fuse holder for cracks, corrosion, and other damage. Check fuse for burned out condition.Check fuse for continuity if in doubt.Inspect brush assembly for corrosion and excessive wear.3-18
