NO OUTPUT
No alternator output detected.
Check all connections to and from the alternator,
especially the connection 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. (Older vehicles use
external voltage regulators, which may require only
replacement of the voltage regulator.)
3
LOW OUTPUT
Alternator not providing sufficient to power the
system's electrical loads and charge the battery.
Check the belts to ensure the alternator is rotating
with the engine running. Replace broken or slipping
belts and retest.
Check the connections from the alternator to the
battery. If the connection is loose or heavily corroded,
clean or reparable the cable and retest.
4
HIGH OUTPUT
Alternator voltage output exceeds the normal limits.
Make sure there are no loose connections and the
ground connection is normal. If there are no
connection problems, replace the regulator. Most
alternators have a built-in regulator that requires
replacing the alternator. In older vehicles that use
external voltage regulators, you may need to replace
only the voltage regulator.
5
EXCESSIVE
RIPPLE
Excessive AC ripple detected.
One or more diodes in the alternator are not
functioning or there is stator damage.
