If the prompts are skipped over by
pressing the +/Up key then a prompt is
displayed indicating that the alternator
and the tester should at this point be
connected to the bench. After verifying
that the setup is correct press the Y/
Enter key to continue.
Some alternators have a remote sense
post to enable the alternator to regulate
the voltage at the battery instead of
at the alternator. If the alternator has
a remote sense post then the remote
sense post must be attached to the
output post of the alternator to test
the alternator on the bench. Otherwise
the alternator’s regulator will not be
connected and the alternator’s output
voltage will be high.
