When my car is just cruising along, the voltmeter will sometimes fluctuate by a few volts.
At idle, the voltage will fluctuate more, occasionally going down below 12 volts.
Regardless of engine speed, the turn signal or brake lights will cause a voltage fluctuation and a slight dimming of the headlights.
Voltage regulator bad? Alternator? Something else?
It's got an almost new Optima battery in it.
