NO CHARGING VOLTAGE
The alternator is not providing charging current to the battery. Check
the belts to ensure the alternator is rotating with the engine running.
Replace broken or slipping belts and retest. 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.)
CHARGING VOLTAGE LOW
The alternator is not providing sufficient current for the system's
electrical loads and the charging current for the battery. Check the
belts to ensure the alternator is rotating with the engine running.
Replace broken or slipping 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 working condition, replace the alternator. (In
older vehicles that use external voltage regulators, you may need to
replace only the voltage regulator.)
CHARGING VOLTAGE HIGH
The voltage output from the alternator to the battery exceeds the
normal limits of a functioning regulator. Check to ensure there are no
loose connections and that the ground connection is normal. If there
are no connection problems, replace the regulator. (Most alternators
have a built-in regulator requiring you to replace the alternator. In
older vehicles that use external voltage regulators, you may need to
replace only the voltage regulator.)
The regulator controls voltage output based on the battery voltage,
under-hood temperature, and vehicle loads used. In other words, it
controls the maximum voltage the system can produce based on the
current needs and amount of current that can be produced by the
spinning of the rotor in the alternator. The normal high limit of a
typical automotive regulator is 14.7 volts +/– 0.5. Refer to the
manufacturer specifications for the correct limit, which may vary by
vehicle type and manufacturer.
