Step 15.

Check resistance of rotor field circuit according

I f ohmmeter reading falls outside 4.5-6.5 ohms,

r o t o r i s d e f e c t i v e . R e p l a c e rotor, reassemble

g e n e r a t o r in accordance with paragraph 3-3, and

g o to step 16.

NOTE

Replace stator only if all previous checks

i n d i c a t e that all generator components

were not defective.

I f ohmmeter reading is between 4.5-6.5 ohms,

r o t o r i s n o t d e f e c t i v e . Replace stator,
