CHARGING SYSTEM
ACCESSORY LOADS
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 issues,
replace the regulator. Since most alternators have the
regulator built-in, this will require you to replace the
alternator.
CHARGING SYSTEM LOW WHEN TEST WITH
ACCESSORY LOADS
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. 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 working condition, replace the
alternator.
CHARGING SYSTEM NORMAL WHEN TEST WITH
ACCESSORY LOADS
The system is showing normal
output from the alternator. No
problem detected.
