On the first screen, the Scan Tool didn’t detect that the
engine had started, so there isn’t a KOER voltage read-
ing.
The second screen did detect that the engine had
started so there is a KOER reading.
The screen on the left shows that the KOEO voltage
before an engine start was attempted was 12.2V. Once
the starter began cranking the engine, a cranking voltage
of 10.4V was measured. After the engine started, a KOER
voltage reading of 14.7V was measured.
•
If the KOEO voltage is very low, this could be an
indication of a bad battery, or one that needs to be
charged.
•
If the cranking voltage is a lot lower than the KOEO
voltage, than this is an indication of a worn starter.
•
If the KOER voltage is not higher than the KOEO
voltage, than this indicates a bad or weak alternator.
