Where should my Volt meter read if everything is good?

On the Aftermarket Voltmeter I just installed,While driving it read right on 14 Volts. What are the absolute limits I should look for to determine Overcharge and Undercharge?

absolute? 13-15volts. While running. Normal will be 13.5-14.75 depending on your particular system (Voltage regulator has a lot to do with the high limit)

Why start another post. You already have one running on these guages.
