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.
