Charging System Check

  1. Check the battery is in good condition, with an open circuit voltage of at least 12.6 volts. Recharge or fit a charged substitute battery to carry out test.
  2. Check drive belt adjustment and condition. Rectify as necessary.
  3. Check battery connections are clean and tight.
  4. Check alternator connections are clean and tight.
  5. Ensure that there is no continuous drain on battery due, for example, to interior, underhood or door edge lamp being left on. If system checks okay, perform on-vehicle testing. See ON-VEHICLE TESTING  .
