10. Press the «ENTER» key to continue the charging system with
accessory loads. One of the three results will be displayed along with
the actual testing measured.
CHARGING SYSTEM HIGH WHEN TEST WITH ACC. LOADS
The voltage output from the alternator to the
battery exceeds the normal limits of a functioning
regulator. Check to ensure there are no loose
connections and that the ground connection is
normal. If there are no connection issues, replace the regulator.
Since most alternators have the regulator built-in, this will require
you to replace the alternator.
CHARGING SYSTEM LOW WHEN TEST WITH ACC. LOADS
The alternator is not providing sufficient current for
the system's electrical loads and the charging
current for the battery. Check the belts to ensure
the alternator is rotating with the engine running. If
the belts are slipping or broken, replace the belts and retest. Check
the connections from the alternator to the battery. If the connection is
loose or heavily corroded, clean or replace the cable and retest. If the
belts and connections are in good working condition, replace the
alternator.
CHARGING SYSTEM NORMAL WHEN TEST WITH ACC. LOADS
The system is showing normal output from the
alternator. No problem detected.
