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.
