(12) Connect negative battery cable to battery, and close BATTERY ACCESS door. d. Installation. (1) Install rotating rectifier (14, Figure 5-9), lockwashers (13), and bolts (12) on rotor assembly (28). (2) Install exciter rotor leads, washers (4, Figure 5-11), and bolts (3) on rotating rectifier plate (5). (3) Install main rotor leads and rotating rectifier diode leads, lockwashers (2), and bolts (1) on terminal bolts (9). (4) Install end bell and main bearing, paragraph 5.10.2. (5) Install rear housing panel. Refer to paragraph 4.7.5. (6) Connect negative battery cable to battery, and close BATTERY ACCESS door. 5.10.4 ExciterStator. a. Inspection.(1) Shut down generator set, paragraph 2.11.2. Allow generator to cool to ambient temperature. (2) Open BATTERY ACCESS door (Figure 1-2), and disconnect negative battery cable. (3) Open output box access door (Figure 1-2), visually inspect generator assembly for obvious damage. Check exciter field leads for broken wires and signs of chaffing. b. Testing. (1) Shut down generator set, paragraph 2.11.2. Allow generator to cool to ambient temperature. Inspect Exciter Stator per paragraph 5.10.4 a. (2) Open output box access door (Figure 1-2), and disconnect exciter field leads F1 and F2 from terminals 1 and 2 of terminal board TB8. Refer to Schematic FO-1. (3) Set multimeter for ohms, and connect between disconnected exciter field leads. Multimeter reading should be as shown in Table 5-2. (4) Multimeter reading other than in Table 5-2 indicates open or shorted windings, and exciter stator must be replaced. (5) Connect multimeter between each exciter field lead and generator frame in turn. (6) Multimeter reading of less than infinity indicates defective ground insulation, and exciter stator must be replaced.
