6. Press the «ENTER» key, one of the three results will be displayed
along with the actual reading measured.
LOW CHARGING VOLTS WHEN TEST AT IDLE
The alternator is not providing sufficient current to
the battery. Check the belts to ensure the alternator
is rotating with 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 condition, replace
the alternator.
CHARGING SYSTEM NORMAL WHEN TEST AT IDLE
The system is showing normal output from the
alternator. No problem is detected.
HIGH CHARGING VOLTS WHEN TEST AT IDLE
The voltage output from the alternator to the
battery exceeds the normal limits of a functioning
regulator. Check to ensure there is no loose
connection and the ground connection is normal.
If there is no connection issue, replace the regulator. Since most
alternators have the regulator built-in, this will require you to replace
the alternator. The normal high limit of a typical automotive regulator
is 14.7 volts +/- 0.05. Check manufacturer specifications for the
correct limit, as it will vary by vehicle type and manufacturer.

15 seconds. You will view the screen as follows:
9. Press «ENTER» to look for the amount of ripple from the charging
system to the battery. One of two testing results will be displayed
along with the actual testing measured.
RIPPLE DETECTED NORMAL
Diodes function well in the alternator / stator.
EXCESS RIPPLE DETECTED
HIGH
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.
