5. Press "Enter" again; one of the three results will be displayed along with the current measured reading.
Result: Good No problems have been detected; the system is working
correctly. Press "Enter" to continue the test on load:
Result: State of charge is high! The output voltage from the alternator to
the battery exceeds normal operating limits. Make sure that there are no
loose connections and that the grounding conditions are good. If all the
connections are flawless, replace the regulator. As alternators usually have
built-in regulators, replace the alternator. The normal voltage limit of a typical
car regulator is 14.6 volts +/- 0.05. Check the correct operating limit in the
manufacturer's specifications.
Result: State of charge is low! The alternator is not supplying enough
voltage to the battery. Check the belts and make sure that the alternator is
rotating with the engine running. If the belts slip or are broken, replace them
and repeat the test. Check the connections from the alternator to the battery. If
connection is loose or corroded, clean or replace the cable, and test again. If
the belts and connections are in good condition, replace the alternator.
"ALTERNATOR TEST" WITH ELECTRIC LOADS ON
1. Press "Enter" to perform the alternator TEST on load: switch on the heating, main-beam headlamps,
rear demister. Do not use cyclic loads, such as air conditioning or windscreen wipers.
2. The following screen will appear:
Press "Enter" to proceed. Rev the engine up to 2,000 rpm for 10 seconds;
then press "Enter" again to view the results.
3.The following screen will appear:
4. Press "Enter" to continue testing the system with the accessories on load. One of the following three results
will be displayed, along with the current measured reading.
Result: Good No problems have been detected; the system is working
correctly.
Result: High Charge The voltage output from the alternator to the battery
exceeds normal operating limits. Make sure that there are no loose
connections and that the grounding conditions are good. If all the connections
are flawless, replace the regulator. As alternators usually have built-in
regulators, replace the alternator. Check the correct operating limit in the
manufacturer's specifications.
Result: Low Charge The alternator is not supplying enough voltage to the
electric system and the battery. Check the belts and make sure that the
alternator is rotating with the engine running. If the belts slip or are broken,
replace them and repeat the test. Check the connections from the alternator
to the battery. If the connection is loose or heavily corroded, clean or replace
the cable and test again. If the belts and the connections are in good condition,
replace the alternator.
