Table 3: Alternator Decisions and Recommendations
Decision Action
NO PROBLEMS The system is showing normal output from the alternator. No problem detected.
NO OUTPUT 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 alterna-
tor. (Older vehicles use external voltage regulators, which may require only
replacement of the voltage regulator.)
LOW OUTPUT The alternator is not providing enough current to power the system’s electrical
loads and charge 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.
HIGH OUTPUT
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.)
