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
connection and the ground connection is normal.
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 specifications for the correct limit, as it will vary by vehicle type
and manufacturer.
CHARGING SYSTEM NORMAL WHEN TEST
AT IDLE
The system is showing normal output from the
alternator. No problem is detected.
