Testing



Specific to:

Honda CR-V 2007-2008

Special tool required:



Alternator, Regulator, Battery, and Starter tester (Honda P/N OTC3131)
 

The alternator provides power consuming components with current while the engine is running and maintains the battery charge. The alternator is mounted on the front edge of the engine. The output of the alternator depends on engine speed. When the engine is idling, the alternator operates at approximately half of its maximum output. When the engine is idling with many power consuming components engaged, the alternator may be unable to maintain full battery charge.

The alternator creates an alternating current which is converted to a direct current in the rectifier bridge. The alternator also utilizes a built-in voltage regulator.

  1. Check that the wiring is in good condition.
  2.  
  3. Check for any abnormal noise from the alternator while the engine is running.
  4.  
  5. Check the accessory drive belt for wear or slipping.
  6.  
  7. Make sure the battery connections are good and the battery is sufficiently charged.
  8.  
  9. Connect the alternator, regulator, battery, starter tester (OTC3131), or equivalent, to the battery as shown.

  10.  
  11. Start the engine. Hold the engine speed at 3,000 RPM with no load (in N or P) until the radiator fan comes on, then let it idle.
  12.  
  13. Do the CHARGING SYSTEM TEST.
  14.  
  15. If the voltage is over 15.1 volts and the amperage is less than 87.5 Amps, replace the alternator.
  16.  
  17. If the voltage is within 13.5-15.1 volts and the amperage is 87.5 Amps or more, check the diode condition on the display.
  18.  
  19. If the diode condition indicates BAD, replace the alternator.
