3-35. EXCITER-AUXILIARY GENERATOR ASSEMBLY (cont)
Place lead (3) of meghommeter (2) on one of the commutator bars. Note reading on meghommeter. Contact
each successive bar around the commutator.
If a reading of less than three megohms is obtained, bake armature for 4 hours at 230°F in a convection oven.
Recheck megohm reading after cooling armature to room temperature. If the reading is still low, replace the
This test must be accomplished on both the exciter stator and the auxiliary stator.
Attach lead (1) of megohmeter (2) to lead AA- on stator housing.
Attach lead (3) of megohmmeter (2) to lead A+ on stator housing and note reading on megohmmeter.
Attach lead (1) of megohmmeter (2) to lead FF+ on stator housing.
Attach lead (3) of megommeter (2) to lead F- on stator housing and note reading on megommeter.
If a reading of less than 3 megohms is obtained on the two sets of leads, bake stator for 4 hours at 230F
(110C) in a convection oven. Recheck megohm readings after cooling stator to room temperature. If the
readings are still low, replace stator.
