The tester will test the amount of ripple from the charging system to the battery.
One of the three following results will be displayed along with the actual reading
measured.
RIPPLE DETECTED NORMAL:
The diodes are functioning properly in the
alternator/starter.
NO RIPPLE DETECT:
The diodes are functioning properly in the alternator/starter.
RIPPLE DETECTED HIGH:
One or more of the diodes in the alternator are not
functioning properly or there is starter 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, the alternator may need to be replaced; have
it checked.

Press
to continue testing the charging system with accessory loads. One of
the three following results will be displayed along with the actual reading measured:
ALT. LOAD VOLTS HIGH:
The output voltage 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 good. If there are no
connection problems, the regulator may need to be replaced; have it checked.
Since most alternators have the regulator built-in, this may require you to replace
the alternator; have it checked.
ALT. LOAD VOLTS LOW:

belts to ensure that the alternator is rotating with the engine running. If the belts
are slipping or broken, replace the belts and retest. Check the connection 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, the alternator may need to be replaced; have it checked.
ALT. LOAD VOLTS NORMAL:
The system is showing normal output from the
alternator; no problem detected.
