CHARGING TEST
This test measures the output of the charging systems under load conditions. This information provides
the basis for further charging system tests. It also detects the presence of an open or shorted diode that
causes an output loss of several amps and can cause the failure of other diodes.
Symptomatic Check before Proceeding:
Battery should be in good condition and charged before testing the Charging System.
Check warning light indications.
Check belt condition and tension.
Check all cables and connections.
Check the battery for corrosion and dirty terminals.
Does the battery have a low state of charge?
Make sure all electrical items are off.
Check for Alternator noise.
Select the Charging Test from
the menu
Make sure the Load
Module is connected to
the battery and that the
engine is running. Press
the START button to start
the test.
If there is any connection issue, the
following screen will appear. Check
your connections to the battery and
make sure the posts are free of
corrosion. This screen will clear and
the test will continue once the
connection is correct.
If the engine is not running, the
BVA-460 will detect that and display
the following screen.
