A high charging rate will overcharge the battery and may decrease its
life and cause it to fail. If the battery test decision is REPLACE and
the charging system test shows a HIGH CHARGING VOLTAGE,
check the levels of the electrolyte in the battery. A symptom of
overcharging is battery fluid spewing through the vent caps, which
causes low electrolyte levels and will harm the battery.
DIODE RIPPLE NORMAL
The charging system is functioning within its normal operating range.
EXCESS RIPPLE DETECTED
One or more diodes in the alternator are not functioning or there is
stator damage, which is shown by an excessive amount of AC or
ripple current supplied to the battery. Make sure 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.
An alternator is designed to create the electrical energy necessary to
charge the battery and provide for the vehicle's electrical system
load. Since the alternator creates AC, (alternating current), it must
be rectified into DC, (direct current), to charge the battery and supply
power to the rest of the system. To accomplish this, the alternator
uses diodes which allow current flow in only one direction, changing
AC current to DC current. When one or more of the diodes fail, the
AC ripple current from the alternator to the battery will exceed
normally acceptable limits.
DIODE RIPPLE NOT DETECTED
The analyzer is not able to detect diode ripple through the battery
cables, or the alternator is not spinning.
9. The analyzer will toggle through the charging system test results until
you disconnect.
