CHARGING SYSTEM HIGH WHEN TEST WITH
ACCESSORY 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
ACCESSORY 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
ACCESSORY LOADS
The system is showing normal
output from the alternator. No
problem detected.
