Internal Field Circuit (Testing For Ground)

  1. Remove ground brush, touch one test prod from a 110 volt test lamp to alternator insulated brush terminal and remaining test prod to end shield. If rotor assembly or insulated brush is not grounded, lamp will fail to light up.
  2. If lamp lights, remove insulated brush assembly and separate end shields by removing through bolts. Again test by placing one of the test prods to a slip ring and other prod to end shield. If lamp lights, rotor assembly is grounded and requires replacement. If lamp does not light after removing insulated brush and separating end shields, cause of ground at first ground test was grounded insulated brush.
  3. Install insulated brush holder, terminal, insulated washer, shake proof washer and screw. If parts were not assembled in this order or if wrong screw was used, this could cause the grounded condition.
