EXCESS RIPPLE DETECTED
One or more diodes in the alternator are not
functioning or there is stator damage. Check to
ensure the alternator mounting is sturdy and
that the belts are in good shape and functioning
properly. If the mounting and belts are good,
replace the alternator.
9. 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 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.
