Trouble Diagnoses with
Battery/Starting/Charging System Tester
NBSC0020NOTE:
To ensure a complete and thorough diagnosis, the battery, starter
and alternator test segments must be done as a set from start to
finish.

1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press ªENTERº to begin the charging system test.
4. Start engine.
SEL418X
5. Press ªENTERº until ªLOADS OFF REV ENGINE 5 SECº is
displayed.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for
about 5 seconds, then return to the engine to idle.
Once the increase in engine rpm is detected, press ªENTERº
to continue.
NOTE:
IIf after 30 seconds an increase in engine idle speed is not
detected, ªRPM NOT DETECTEDº will display.
ISome engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect this
without any other action being taken. If this occurs, continue on
with the testing process. The final results will not be affected.

7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the fol-
lowing electrical loads.
