Rebuild exciter rotor as follows: (Seefigure 11-20.)(1)Inspect winding slots for any sharp cornersat edge and in slot. Clean up as necessary.(2)Wind armature coils usingnumber of turns and wire per winding date.(See figure 11-20).(3)Sleeve leads with flexible braided glasstreated sleeving.(4)Apply slot liner insulation 5-5-5 (polyester-mylarpolyester) as shown in slot detail, ItemA, figure 11-20.(5)Make pole series wye connections perwinding diagram. (See figure 11-20.)(6)Insert slot wedge (Item B) in slot as shownin slot detail and extend 1/4 inch (0.35 mm)beyond armature.(7)Make high potential test. Test voltage to be1500Figure 11-20.
