My battery light came on today but the car feels the same. I did notice that the voltage did go down but its within the normal section. Is it the battery? Thanx

Have the voltage on the battery tested and the alternator voltage tested. Someone can chime in as to what the specs should be.

The majority of vehicles that come into work with a battery light on would be the alternator going bad cause it is not putting out proper voltage.

The only vehicles I've seen where the battery light may come on on when the battery is bad has been any dodge/chrysler 01-05.

I think pepboys now sell the 160-200amp alternators. You can always check on ebay also. here is one

Not sure how good these are, but the price is good though

Start your car and us a multimeter on your alt. ground to the alt it self and lift the rubber cover off the nut and touch that see if it is putting out 13+ volts. High voltage is bad too, means a bad regulator. If that goes it can run up to 110 volts
