4.14 Rotor Winding Testing
Before testing rotor, visually inspect windings for dark
streaks which indicate a burned or shorted winding.
Rotate ball bearing by hand. Replace it if it is rough or
noisy.
To check rotor:
1. Remove end cover, locknut, stator and rotor from
generator. See Section 4.15 Generator Disassembly .
2. Unsolder wires from diodes, being careful not to break
wires.
3. Measure rotor resistance as shown in Figure 4-9.
4. Record resistance values of both windings and com-
pare them with values listed in Table 4-1.
5. Check for grounded windings by holding one meter
lead to winding and other lead to metal frame on rotor.
Replace rotor if windings are open, shorted internally or
shorted to metal frame.
