Check that drive end bell (1) has no cracks, warping or other damage. If

drive end bell is damaged, generator is nonrepairable.

Check drive end bell bearing (2). Refer to TM 9-214. Get a new bearing

if it is damaged or worn.

Check that screws (3) are not bent or broken and that they have no damaged

threads. If screws are damaged, get new ones.

Check that rotor (4) has no grounds by using a multimeter and touching one

test probe to rotor shaft (5) and the other to one slipring (6). Ohmmeter

readings must be more than 10,000 ohms. If reading is not more than 10,000

ohms, generator is nonrepairable.

Do step 4 again for other slipring (6).

Check resistance of sliprings (6) by using a multimeter and touching ohm-

meter probes on each slipring (6). Resistance must be between 7.0 and

7.8 ohms. If not within given limits, generator is nonrepairable.
