I finally checked out what voltage my car is putting out when I am driving the car.

When the engine is off the voltage reads 13.25 volts

When the lights are dim the voltage reads 13.22 - 13.61 volts (this is when the car is on and driving)

When the lights on my car are at their brightest the voltage reads 17.77 - 18.02 volts (this is also while driving)

Now to me this would be the voltage regulator. The cheapest I could find was $75.00. The dealer wanted $96.00. So before I buy it I wanted to make sure that this was the problem or do I need to change the whole alternator.

Thanks
