Bench Testing: Brushes

  1. Inspect brushes for free movement in holder. Clean brush holder if necessary. Check brushes for cracks and wear. Check brush springs for corrosion or damage. Test brush holder to ensure no continuity exists between holder and brush.
  2. On Isuzu Impulse, wear limit is .22" (5.6 mm). On Isuzu diesel engine alternators, wear limit is .55" (14 mm). On all other alternators, replace brush holder assembly if brush wear has reached limit line on brush.
