1. The tester asks «SWITCH CONSUMERS ON AND PRESS ENTER». Turn on the heater to maximum (heat), high
and rear headlights. Do not switch on cyclic loads such as air conditioning or windshield wipers.
2. Run the engine at 2500 rpm for 15 seconds.
3. Press «ENTER», the undulation of the charging system appears. One of the two results is displayed :
Results found
Normal undulation intensity
High undulation intensity
4. Continue the test by pressing «ENTER». The tester now analyses the charging circuit with the
consumers of the running vehicle.
• Result of the load system test with consumables running
Examples
High starting voltage when the
test is performed with the consu-
mers running
Normal starting voltage when
the test is performed with the
consumers running
Low starting voltage when the
test is performed with the consu-
mers running
6. The test provides a printout of the test results of the alternator charging system. Press «ENTER» to start

The diodes are working in the alterna-
tor/starter
OR
One or more diodes are not working or
are damaged. Make sure that the
alternator support is properly
positioned and that the timing belts
are working properly. If so, replace the
alternator.
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 problem 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.
The printout does not work for the 24 V battery system
tests. Follow the steps below to print the results:
1. Perform the system test on a 24 V battqery.
2. When the test is complete, connect the tester to a
single 12 V battery (the 24 V system test results remain
stored in the unit).
3. The unit displays «PRINT 24 V SYSTEM TEST?»
4. Select «YES» to start printing or «NO» to return to the
main menu.
