Normal Regulated Voltage Range
 

When monitoring system voltage while driving, I'm seeing voltage vary from the low 14s, to up to 15 volts (seen 15.2 several times). That seems to be on the hot side to me. My question is, how high is too high? What is normal voltage regulation for a 2010 Dodge Charger (police package)?

That sounds pretty typical. The gauge isn't the most accurate thing in the world...... If it gets to high/low, the PCM will complain. :)

Thanks. I just seemed high to me.... Not that it matters... The car don't have a gauge.. it was measured via a DMM
