displayed along with the actual reading measured.
LOW CHARGING VOLTS WHEN TEST AT IDLE
The alternator is not providing
sufficient current to the battery.
Check the belts to ensure the
alternator
engine running. If the belts are slipping or broken,
replace the belts and retest. Check the connections
from the alternator 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
condition, replace the alternator.
CHARGING SYSTEM NORMAL WHEN TEST AT IDLE
The system is showing normal
output from the alternator. No
problem is detected.
HIGH CHARGING VOLTS WHEN TEST AT IDLE
The voltage output from the
alternator
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.
