Under normal conditions, a 12V battery is fully charged at 12.8V. A slightly higher reading
may occur under the conditions outlined in the last step, but, generally speaking, any
reading above 12.8 when the engine is stopped is not a true reading.
ENGINE RUNNING FAST ENOUGH TO MAKE ALTERNATOR PRODUCE CHARGE
Disconnected voltmeter. Engine could not run with dead or disconnected battery unless
circuit was completed around battery.
