HIGH CHARGING VOLTS WHEN TEST AT IDLE
The voltage output from the alternator to the battery exceeds the normal
limitsofafunctioningregulator.Checktoensurethereisnolooseconnec-
tion and the ground connection is normal.
If there is no connection issue, replace the regulator. Since most alternators have the regulator built-in, this
