Visual Inspection of Field Coils
If the insulation on the field coils appears blackened or charred, the serviceability of the coils is questionable.
Burned or scorched coil insulation indicates the starter/generator has overheated due to overloads or
grounded or shorted coil windings. Be sure the insulators are tight in the housing.
Starter/Generator Rework
Any rework must be performed by a qualified technician. Starter/Generator service specifications are listed in
the following table.
ITEM
Commutator diameter (minimum)
Concentric with armature shaft
within
Limit depth of cut when
machining commutator
If undercut of segment insulator
is less than 0.016 inch
(0.406 mm), then it should be
undercut to:
Dielectric strength
Armature insulation resistance
Starter field coil resistance
Generator field coil resistance
