Good Maintenance Practices:

  • There is a cooling fan in most alternators to keep it from overheating. Making sure that the fan is clean will help the fan and alternator run properly.
  • It is also important that all electrical connections are kept clean and firmly attached, which will make sure the battery is being properly charged by the alternator.

When making repairs on electrical systems, in-depth diagnosis is needed before parts replacement. This includes checking:

  • Grinding or squeaking noise
  • Alternator warning light illuminates
  • Bad battery
  • Broken, frayed, or loose drive belt
  • Electrical fault
  • Worn or damaged bearings
  • Corroded or loose battery terminal connection
  • Burned fuses or fusible links
