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.

Troubleshooting Tips:

  • Indicators that there could be a problem with your vehicle's alternator are:
  • Engine doesn't turn over or start
  • Loss of battery power
  • Some loss of electrical power (dimming headlight, etc.)
  • Grinding or squeaking noise
  • Alternator warning light illuminates
  • Other vehicle parts that might cause related alternator problems include:
