Best Practices
  • It's not uncommon for batteries and/or alternators to be replaced when they really don't need to be. Any of these parts can cause similar symptoms, so to avoid unnecessary replacement, have the battery, alternator, and battery cables properly tested.

Common Symptoms
  • A poorly performing charging system can result in various warning lights to illuminate, starting problems, and emission system test failures.

Common Misdiagnoses
  • The battery must be fully charged to properly test the alternator. Testing with an inadequately charged battery can lead to the replacement of a perfectly good alternator.
