eddie bauer 97 explorer charged the battery and put in a new alternator battery not hold a charge
Are you sure the alternator is putting out the correct voltage and or the battery is strong enough to hold the charge? Get a multimeter, probe the battery itself. Is it 12.4V or better, and no more than 5 years old? If it's lower or old, time to replace. No charging will help it. Have your local auto parts store check it for you for free. Then with the truck on, probe again, is the voltage 14V or higher? If still at 12 or lower with truck running, the alternator needs replacing.
