Press «ENTER» to read the ripple from the charging system to the
battery. One of the three testing results will be displayed along with the
actual testing measured.
RIPPLE DETECTED NORMAL
Diodes function well in the alternator /
starter.
NO RIPPLE DETECT
Ripple is not detected.
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.

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.
