When I test battery voltage while the engine is running what should it be? I seem to remember it being in the 14 volt range. Is it higher as the revs go up? The Bentley didn't help or I just couldn't find info in there.
That's assuming the cigarette lighter voltmeter is accurate.Mine ranges between 14 and 14.4 depending on what accessories I have running.

It should never be less than 13.2 for the typical voltage regulator or above 15, and even that's a bit high. 13.5-14.5 is more typical.When I test battery voltage while the engine is running what should it be?

Mine is similar monitored thru the ScanGauge.That's assuming the cigarette lighter voltmeter is accurate.
