Bench Testing: Stator
Check stator for short circuits. If one or more coils are burned, stator shows evidence of shorts. Connect 12 volt, brush holder frame and "-" brush. Lamp should give steady light. If test results are not satisfactory or brush length is less than 3/16" (5 mm), replace brush holder.
CAUTION:
Use only specified test lamp. Do not use 110 or 220 volt test lamp on this or any other alternator test procedure.
