Translation of the original instructions
• Result of the start voltage test
Result
High starting voltage when the test is
performed with the engine at idle
Normal starting voltage when the test
is performed with the engine at idle
Low starting voltage when the test is
performed with the engine at idle
5. The tester will prompt to «TURN ON CONSUMERS AND PRESS ENTER». Turn on the heater to maximum (heat), full
beam lights and rear headlights. Do not switch on cyclic loads such as air conditioning or windscreen wipers.
6. When the test is done, run the engine at 2500 rpm for 15 seconds.
7. Press «ENTER», the undulation of the charging system is visible. One of the three test results is displayed:
Result
Normal undulation detected
No undulation detected
High undulation intensity
8. Press «ENTER» to continue the charging system test with the consumers running (lights, heating ...).
• Charging system test result with consumers running
Examples
High starting voltage when the test is
carried out with consumers in operation
Normal starting voltage when the test
is performed with the consumers in
operation
Low starting voltage when the test
is performed with the consumers in
operation
9. Press «ENTER» when the system test is complete. Turn off all consumers (heating, lights, etc.). Press «ENTER» to
obtain the test results. Use the buttons

Analysis
Check that the connections are good. If every-
thing is properly connected, replace the regulator.
No problem detected. Normal operation of the
alternator.
The alternator does not provide enough power
to the battery. Check the belts, and ensure that
the alternator is running when the engine is
on. If the belts slip or are broken, replace them
and re-test. Check the connection between the
alternator and the battery. If the connection is
bad, clean or replace the cable and re-test. If
the alternator belts and connection are in good
condition, replace the alternator.
Analysis
The diodes are working in the alternator/starter
No undulation detected Alternator malfunction.
Replace it.
One or more diodes are not working or are da-
maged. Make sure that the alternator support is
properly positioned and that the timing belts are
working properly. If so, replace the alternator.
Analysis
The alternator output voltage is abnormally high.
Check that there are no connection problems. If
not, replace the alternator.
The alternator output voltage is normal. No
problems are detected.
The alternator does not provide enough current
for charging the electrical system and the battery.
Check the alternator belts, and make sure the
alternator is running when the engine is running.
If the timing belts slip or are broken, replace the
timing belts and re-test. Check the connection
between the alternator and the battery. If the
connection is bad, clean or replace the cable and
re-test. If the belts and connection are in good
condition, replace the alternator.
