Interpretation

System is showing normal output from the alternator.
2
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.)
