    Voltmeter fluctuates, why?

    Recently i've noticed that my voltmeter needles bounces around 14 volts. While this is happening the dash lights and also the car lights pulsate. Is this an early sign that my alternator is going bad? Or is it being caused by something else? Any help is appreciated.

    This is pretty common it seems, I have seen other threads on this topic and usually it is recommended that you check all your connections from your alternator and check your serpentine belt.
