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connec-
tion and the ground connection is normal.
ALT. IDLE VOLTS
xx.xx V HIGH
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specicationsforthecorrectlimit,asitwillvarybyvehicletypeandmanu-
facturer.
CHARGING SYSTEM NORMAL WHEN TEST AT IDLE
The system is showing normal output from the alternator. No problem is
detected.
