Alternator Brushes


  • On some older vehicles, if only the brushes are to be serviced, the rest of the alternator will not have to be disassembled. However, newer alternator will require removal of the unit and separation of the case. Properly identify your alternator before beginning replacement procedures.
  • Some alternators have brushes that can be replaced from the outside, without splitting the alternator housing.
  • Brushes are spring loaded.
  • When they wear, spring tension becomes less.
  • Brushes that are too short can cause an alternator to stop working intermittently (once in a while) before failing completely.
