Check that rotor shaft (1) has no burred or stripped threads.

Check that rotor (2) has no grounds using multimeter by touching one test

probe of multimeter to rotor shaft (1) and other test probe to one slipring

(3). Ohmmeter reading must be more than 10,000 ohms. If ohmmeter reading

is not more than 10,000 ohms, generator is nonrepairable.

Do step 2 again for other slipring (3).

Check sliprings (3) resistance using multimeter by touching test probes of

multimeter to each slipring. Resistance must be between 1.8 to 2.0 ohms.

If resistance is not within limits, generator is not repairable.

Check sliprings (3) runout. Refer to para 2-9e.

Check that rotor shaft (1) is straight. Refer to para 2-9e.
